Brainstorming...what if the entire IFS assembly was mounted in a ridgid frame (along the lines of Atomic Axles), with the control arms fixed in position? Then the whole setup is coil sprung. Would allow a high-clearance front axle. There's something called a De Dion suspension that uses a beam axle and a separate drivetrain assembly, sort of like this.
