I already do this. I use Evolution mostly for mailing lists, and the
Gmail web interface mostly for personal stuff. That's a big reason I
prefer IMAP to POP, because it Just Works (tm).

IMAP allows you to delete mails for one MUA and to keep it for the
other MUA, used for another purpose? 

That is wrong. With IMAP the mail is stored on a server and each MUA
interrogates that server for the mail information. When a mail is
needed its body is downloaded. Some MUAs may then cache a copy of the
mail locally, but the definitive version is still, and always, the
version that's on the server. So no, you can't delete a mail on one MUA
and it still bre available on another.

IOW any kind of sync has got it's
pros and cons. 

IMAP is *not* a sync protocol. It is a client-server arrangement. The
only 'syncing' that goes on is if the MUA does some form of off-line
queuing of changes, at which point when the server is recontacted the
information is synchronised. BUT there is nothing in the IMAP protocol
to sort out in-coherencies and arbitrating between multiple client
inconsistencies.
