I think this is a fine idea, but here's the list of devices with issues:

ws, sd, ld, cd, raid, ccd    -> minor numbering issues (there might be
                                even more)
clockctl, systrace, cgd,
wsfont, dpti, irframe,
ksyms, mly, joy, cir,
radio, kttcp                 -> different (and overlapping) major
                                numbers.

(This is a quick read of diff {amd64,i386}/conf/majors.*, I might be
missing a couple devices.)

That means we'd burn that many MI (or maybe MD--yet common to i386 and
sparc64) major numbers to solve that issue.  Is it acceptable?
