Unfortunately a floater, outboard shocks and weight jacks are rule issues. While it may work at some tracks, other tracks will deem the car illegal.
I used to have a car that was built the way Eric is thinking. It really isn't any departure from the norm, it just makes the hoop in the front replaceable in a matter of minutes rather than having to cut and weld. We did some other thing to the chassis to make it more user friendly as well.
