I believe the lower control arms are different on the coil sprung D3 compared to the air sprung ones, so you'd need to swap them over, at no small cost. The upper mounts are integrated with the chassis, and appear to be the same for both types.

Wiring in an aftermarket controller would be difficult, given how integrated the rest of the electronics are.

As already stated, would be easier and cheaper to just sell the coiler and buy an air sprung one instead.
