Tony,
You touched on one of the avenues I've been looking at in your discussion, but it still needs to be thoroughly-tested before it can be deemed viable. It's the most practical one, and several designs in buttstock/cheek geometry currently would support it. One of the challenges with the top-mount magazine design I ran into is magazine capacity for assault rifle cartridges, which the 5.7 easily overcomes being so small. It's very difficult to get a 30rd magazine into that P90 style configuration when dealing with a .444" cartridge base.
