I assume you have some good reason for not using PMX, but nevertheless
I'll point out that PMX does what you seem to want to do, i.e., allows
you to change the width later with no trouble. It does this by
internally running its own musixflx-like calculations, taking account
of the width of (practically) all symbols to be printed. It does this
first at a slightly crude level to determine where the line breaks go,
and then at a more refined level on a second pass when inserting space
to avoid crashes. (And even if the more refined calculation is not
exactly right, it doesn't usually matter because musixflx itself will
smooth things out while still respecting the linebreaks that PMX
dictated).
