Adding extra ram in A2000 with a2630

[DoogUK]

Ok no doubt this has been asked before...but here goes.

In my A2000, i have an a2630 accelerator with 4mb ram onboard and a GVP series hd+8 with 4mb onboard.

I know the zorro bus will only address 8mb max...but is there any way i can add the extra 4mb to the GVP and make it useable?

I wish i had the skills to build an expansion myself..i know the fast ram exansions for these accelerators are rare and command huge sums of money.
