Doppler ER3 for SPX (1 reply)

Hi, I have a Doppler ER3 variator for Peugeot spx, Doppler # 292555.

This doesnt fit on a regular 103 crank as the variator side is different.
Is there anyway to make this fit on a regular 103 crank? I know I should get the #292521 but im just checking if there is a way to mod it to make it fit. Like can I change the shaft out so it fits?

THanks in advance.
