Reportedly it has been done
Good to know about the rod bolt clearance. Boring out the A12 to use 76mm pistons is likely required. Preferaby a short-skirt piston so that crank machining & rebalancing is not required
The side clearance is a well-known issue. The A14/A15 block is notched inside (very slightly) to clear the crank throws. Hard to tell the difference by eye, so perhaps the A12 block can be likewise clearanced
The A15 oil pan bolts up to a late A12 or A12A block
