The 'standard' Crossflow capacities were all achieved by using the same bore (80.97mm) with a variety of different crank strokes.

Yours will have been based on the largest standard crank throw (76.62mm) with an overbore for 85mm pistons.

If you try to keep your 85mm pistons, but use a 1300 crank, you'd end up with 1429cc.

If you try to keep the crank, even with the standard bore and pistons you're obviously back to where the engine started out: as a 1600.

Short answer: re-using those components is not practicable.
