I have a couple of questions. I'd like to build a 6x7cm view camera
with groundglass focussing, like the Bender but smaller, but I'd like
to use Hassselblad or Kiev 88 backs.

This camera already exists, a baby graphic. :-)

Also the backs you mentioned are 6X6, the gearing is different between the
two and the body advances the film. I'd -highly- recomend avoiding the kiev
backs, it's the worst part of a bad camera! :-)

Something like the 2X3 graphloc back stolen off a baby graphic or the back
off of a graphlex would be a much better place to start.
