You seem to assume that the same features for the same lexical
representation lead to exactly one Form. I don't think this is required. In
fact, we can have different forms with identical features but differences
in usage. Think of English "has" and "hath", which probably should be two
forms. Despite both being 3.sg.ind.prs, they are not interchangeable.
Looking at your examples, these forms also differ *phonologically*, not
just orthographically. There are at least five phonologically
differentiable forms here:

"ECVPETARIS", "ekupetaris",
"epetaris", "eppetaris"

Everything else is just orthography. If your resource *decides* to define
forms as phonologically-based (this is not required), these would probably
be it.
However, this is pre-standardized writing, and you could go as far as to
distinguish every attested form simply because you can *never* be certain
whether there really are no phonological differences (epe- vs. eppe- may be
a difference, for example).

This approach would give us something like (elipsis added for readability):

I personally see no issue with that. The implicit assumption in this
modelling would be that the form variation is basically orthographical.
This is exactly what frac:quotation is there for, and there are other forms
of orthographic variation that aren't captured either in the writtenRep
(e.g., clitics). Modelling it in this way would mean that your form is
something abstract (whether you make it explicit with a transcription or
not), i.e., a continuum of evolving forms from a particular base form,
*ekwopetaris (> *ekwəpətar(ə)s  > *epəpətar(ə)s > *epətar(ə)s or the like
-- I made the glossing up, sorry for that -- is that "four horses"
[quadriga?] in Faliscan?).

As far as I see, OntoLex(-FrAC) allows you to *either* distinguish
different graphic representations as different forms (if that's important
for the data provider) and with their respective attestations -- that would
be the epigraphical approach --, *or* to lump them together in one form and
then indirectly cross-reference them by giving their respective full forms
-- that would be the etymological  approach --, *or* try do assert
different phonological forms, each with multiple writtenReps (as I tried
above, this is the phonological approach). Everything beyond that would be
beyond OntoLex-FrAC. You *could*, however, think about introducing
identifiers for different orthographical systems and then cross-reference
them (however, writtenRep is a datatype property and cannot take further
arguments that your orthography identifier could resolve against).

The difficulty I see is how to create a resource that is *both*
epigraphical and etymological (or phonological) at the same time. But on
the other hand, I don't see how something like that would look in a
dictionary. If you have such data, please share it, and we can consider to
take this as a basis for an alternative modelling.

The only place to keep that information would be in a form. writtenRep is a
datatype property. No metadata!

No, owl:sameAs would conflate them (or, reasoners would). We would need
another property. In principle, the right place for such a property would
be vartrans, and it should be a LexicalRelation between different forms.
There is no such thing, but we would generally need it for historical data,
e.g., etymological dictionaries. I would prefer this very much over
inventing something complicated within FrAC. Also because it would make
vartrans more symmetric, i.e., just applicable to every core element.

Until we have that, we can resort to skos:related to indicate that
different forms with the same etymology (and, possibly, phonology -- we
don't know that for sure, though) have more in common that just the same
grammatical features.

Using that, we can *actually* provide etymological and epigraphical
analyses at the same time, using the reconstructed "underlying" form as the
one from which the other related ones depart, and possibly give it some
special property to mark it as reconstructed (which would be outside FrAC,
as well -- maybe within morphology or lexinfo?).

I would rather avoid that. For many reasons: I'm not sure we can axiomatize
the values of datatype properties in this way. It would create something
nearly identical with Attestation, leading to a lot of confusion among
users of FrAC. If this is an observable, this would mean that it can have
Attestations on its own right -- what is an Attestation of an
AttestationRep? It would introduce at least two new properties and one new
class (as opposed to just one reifiable vartrans property that uses the
same construction template as we previously used for lexical relations),
and it would be *highly specific* for a use case relevant for epigraphy --
but not much beyond that (I might be wrong on that one). For a vartrans
relation between forms, I can see other uses (e.g., systematic mappings
between related forms of different lexemes, e.g., from different
languages). For the attestationRepresentation, I'm not sure these do exist.
