No, because "gaulish" is not a registered variant subtag and probably
never will be.  So "cel-Grek-gaulish" is well-formed but not valid.
(Script tags are four letters long.)

As for "cel-gaulish" itself, it's syntactically regular, but semantically
grandfathered: it means not "some unspecified Celtic language in the
unknown variety called 'gaulish'", but rather "Gaulish".  In RFC 4646bis
there will be regular non-grandfathered tags for Transalpine and
Cisalpine Gaulish, and perhaps one for Gaulish as a whole
(in which case "cel-gaulish" will be deprecated).  In the end
we hope to have all the grandfathered tags deprecated except
"i-default", which plays a very special role.
