This is certainly possible. The catch is that I suspect you'll find that people don't know how or aren't able to encrypt to a particular subkey some of the time, and a different subkey the rest of the time. GnuPG does, but not all OpenPGP programs have the ability to pick which subkey to encrypt to.
