I think you would run into issues, since to get a screen with the hole size small enough to be effective, it would clog pretty quickly. Where as with a sponge, there are particles that get trapped up against the front, as well as inside.
I don't think the biological filtration capacity is an issue, it just won't be fully utilized. having the extra substrate for bacterial colonization certainly won't harm anything.
If anything, it would probably just work to scale the mattenfilter down, maybe use a smaller corner unit or something
