That's exactly what grouping will do. At least for the first sentence. You
can ask for many items in each group, display only the first and store the
others "somewhere", for later use. When you reach your "merchant
representation  threshold" (say 50% of total number of groups) then you can
start picking the items you stored "somewhere" to display them at randomly
chosen positions. That won't help pagination, though.

Could that help you ?
