I want to use pistons from RB25 but use forged 119.5mm connecting rods and additionally adapt the pistons to the NEO head.

Hello ! I'm building an engine for my Skyline R33. I want to use the RB26 shaft in the RB26 block. Configuration: RB25 S2 engine block RB25DET NEO cylinder head Mahle Motorsports RB25DET S2 87.00mm forged pistons Forged H-Beam connecting rod 119.5mm Crankshaft RB26DETT Will this configuration be ok? I'm still thinking about converting the pistons from S2 to NEO pistons using a milling machine. I'm worried about the compression ratio. I already have all the parts except the connecting rods.
