That is not as silly as you might think. Actually to make an 8 bit ISA bus 
interface is easy. The hardest part is to get older 8 bit video cards and data on 
them to write drivers for them. That thought has crossed my mind.

Then you no longer are slaved to the video logic contained within the GIME 
Chip. The one major draw back is that these video cards often have address 
ranges in the lower part of memory that would need to be translated up.
