Some drawings or sketches might help here to visualize what you have in mind. But if I understand you right (which I probably don't - not enough coffee yet this morning), it seems to me what you have here is a "twin beams" setup (I think Flaming River now makes something like this). But due to the short length of your axles, I think you are going to end up with some real camber problems and some bump steer issues as well. The Flaming River axles are half the width of the front track (they meet in the center) and the old Ford twin beam set ups have overlapping axles - to get even more travel radius and reduce camber fluctuation.
Again, a sketch would help. But I think what you are trying to do will get very dicey in terms of geometry.
