Technically this would count as having 4 driven wheels, only that the front are being enabled to drive in reverse. Therefore not legal.
The following I found in the BRCA rules on their website:
23.1 Two wheel drive cars (2WD) are those having only one pair of driven wheels on the same axle. Either the front or rear axle may be driven. Four wheel drive (4WD) cars are those having all four wheels driven.
Check the BRCA rules for any other ideas, but ultimately you would still need to pass it by the BRCA first even if you do find a loop hole:
23.12 The use of sensors fitted to wheels, lay-shafts or suspension units to aid traction control or active suspension is prohibited. The use of the third channel parameter on a receiver is limited to external power supply only (no signal circuitry allowed).
23.13 The 1/10th Off Road Committee are empowered to legislate at any time against any new equipment that in the opinion of the committee detracts from the essential skill of the driver controlling the car during racing. Manufacturers, importers and others are therefore strongly advised to consult with the 1/10th Off Road Committee before investing in technology that may be ineligible.
