Mind you that synchronising tasks with multiple chips are not that easy.
Also it might be easier to use similar products so that you do not need to
deal with everything -- most engineers cannot deal with different chips
equally good (or bad). And as all things has issues you might need to build
up experience on one platform (or limited number of platforms) so that you
can have a better chance to know that selected things in more detail.

So if you think AVR is better for your needs you most probably do not want
to mix it with PICs in my opinion.
