15MB kernels on i386 isn't a problem.

I have a NetBSD/i386-based kernel that's 7.5MB compressed and 23MB
uncompressed, which contains a 20MB md0a / file system (15MB used).

I know that it's possible to fit an entire "base + etc sets"
embedded md0a / ramdisk on a NetBSD/i386 system; the
resultant kernel is about 108 MB.

There _used_ to be a bug that prevented such kernels from
working on NetBSD/i386 where the total kernel size exceeded
around 15MB, but that was fixed a couple of years (?) ago.
