Sounds feasible, but there are some snags to watch out for:

 - distributions tend to customize the kernel; some more,
   some less.
 - different distributions come with different kernel
   versions: if the versions don't differ too much (e.g.
   they get along with the same libc version) that might
   not bite you

Expect some tinkering.
