Yes, this would be legal.  

The Math WG had a session on types at its last meeting, and the
outcome was that several WG members are drafting a W3C Note on best
practice for indicating types.  Maybe one of those people could chime
in, and comment on your proposal.  [hint, hint]

I also want to respond to Stan's comment, that it is probably not good
to start recommending naked presentation markup withing content
markup.  So, then, maybe the thing to do is put an ms inside a ci:

<ci><ms>asdf</ms></ci>

This is also legal, right.  

One other point.  Using the ms tag will have the effect of rendering
the contents in quotes by default.  Thus

<ci><ms>asdf</ms></ci>

would render as

"asdf"

If that isn't what you want, then ms is not for you.  (Note, you can
customize the quote characters with attributes).
