I don't think that it would stop at just the empty admiral spots. If the Navy's going to have a draft they might as well go all out and expand instead of just copy the number of the previous regime. I don't know about more admirals considering the authority they have but doubling the overall military strength through the draft would be cool.

Oh and as far as noone wanting the Admiral positions I think you're forgetting Aokiji who seemingly roamed whereever he wanted dispatching lazy justice.
