Not exactly "as is", but definitely doable.
Easiest would be to "sidegrade" to another machine, where you setup
with MS from the outset, but that would be utopian, I suspect:-).
Do read the setup instructions (both on the website and in the wiki)
very carefully... When using PF, you'll likely be running as an
unprivileged user, so all concerning that has to be exactly right...
I'd work on a copy of /etc/postfix, so that when the big bang moment
arrives... I could switch between the two with a few mv operations.
It's been quite a few years since last I touched an amavisd (of any
kind... I'm a happy MS customer:-), but you might need take it offline
when installing MS, if the MS install messes up any "common" perl
modules.

Ew.
