Most things are possible :).

The implementation isn't hard, maintaining some kind of translation
table for the dependencies, shared library provision lists and so on is
a *lot* of work though.

It would really take someone with a specific use case to step forward
along with manpower for it to have a chance of happening. Even then it
would work for a specific set of packages and wouldn't translate to any
other package feed.

Cheers,

Richard
