I really don't see 4x5 as being a restriction for "format." All that is needed is a bit of cropping.
6x6 = 1.0
4x5 = .8
645, 6x8, half frame = .75
8x11 = .72
5x7 = .71
24x35 = .69
6x9 = .66
Golden Ratio = .62
Spend some time with some tape on your ground glass, and then see how your compositions look.
