It appears by the previous posts that the answer is no.
Thinking out loud...the solution would have to dynamically invoke the length of a submatch as a quantifier, or count its occurrences, neither of which seems to be allowed. Or you could cheat and check for every power less than n, in a massive alternation, by building a custom regex before the match. -QM
