Shimano Chainrings on Rotor Spider

[moock]

Is it possible to mount Shimano Chainrings on a Rotor 110mm 4Arm Spider? I want to use P2M Powermeter but don't have the money yet. So i would use the 30€ Rotor Spider instead until i have enough money.
So Rotor Aldhu + Rotor Spider + Shimano rings possible??

No, or at least not without significant modications to the rings.

You mean like the bottom image below? Because the flange/attachment tabs on the Shimano cranks are not as 'enveloping' as those of the Rotor spider. Not quite related, but when was riding the SRM DA 9000, I was using Absolute Blacks Oval chainrings and had to get new rings when I switched to a Shimano R-9100P simply because Shimano changed the flange profile of one of the four mounting tabs for the R9100/R8000 crank spiders.
