Yes, a 5x7 box unit like the Aristogrid units would be easy to fit into most 5x7 enlargers. Leave the lifting details to the buyer if the enlarger design doesn't take a boxed light source. What you have for the D2 scaled up to 5x7 or 8x10 would fill a hole in the market, as Aristogrid seems to be only making replacement light sources on special orders. Even the Beseler 8x10 conversion used a box light unit that just sits on the adapter. I think you might find there are a lot of us who would be interested in larger units.
