[Cryptography] Mixing public key crypto systems?

Inspired by the 'monoculture' thread, I'm curious as to whether it is possible to mix different public key crypto systems.

For example, Alice might use some version of RSA, while Bob might use some version of El Gamal.

Alice posts her public key in her chosen PK system; Bob posts his public key in his chosen PK system.  Each has to use the type of encryption chosen by the addressee of the message.

Does everything still work?
