I am thinking of filling the old bages with polystyrene beads

Has any of you done this sort of thing, if so any thing to look out
for

My first thought is that, if the old bags let air out, the new bags will let
water IN, and there's no easy way to drain them. You might make them a LOT
heavier this way..

If you don't trust air bags I'd be inclined to go in the solid[1] shaped
foam direction, 'cause that seems to be a working thing you actually see
in use. In the bow you can carve them into an ideal footrest, though
this isn't such a Cunning Plan if more than 1 person uses the boat, or
you want to use the same buoyancy in several boats.
