Is it possible to add them to the A3000 in any way?
I don't know huge amounts about Amiga hardware, but AFAIK it's impossible (unless you happen to have an AA3000 mobo knocking around ;-) ).
---edit---
Here's the same answer from the Amiga History Guide.
It has a graphics-card, can it be used to emulate AGA?
I see no obvious reason why you couldn't run OCS applications through the Amiga port of UAE, but they'd be extreeeeeeemely slooooooooow. Very nicely behaved applications probably won't mind displaying on the GFX card, but AGA games etc will just try to bang the non-existant AGA hardware direct.
