Lower compression so will need rb26 crank.

Nope, been running for almost 2years now in my old s14 with 26 pistons and rb25 crank. I put my knob on a block. True story, does lower the compression by a ball hair, but no big diffrence

Stock RB25DET compression ratio is 9:1 (and 9.5:1 for the NEO).
RB26 pistons drop that to just under 8.3:1 assuming the only change is the 2mm pin height increase and deck height for 8.5 compression in the RB26.

So no, they won't work well.

Well it gave me close to 300 rwkw and she is still going strong. Worked just fine for me.
