Just get yourself a PicassoIV GFX card.
Not only does it have a section where the video slot edge connector can break out and be connected to the remote A2000 video slot, it also picks up Amiga motherboard video from the video slot and scandoubles them so you can use any standard 31kHz monitor.
Plus you can use nice 24 bit screenmodes for workbench and stuff if you want to.
