Rear Foot Stay Compatibility Question

Hey Gents, Just wondering if it's physically possible for the rear foot stays L+R from a B series fit later E series ??
Has anyone tried ? Is it possible the mounting footprints are the same but are just shaped a little different and have a different finish ?

I have no idea, but if they don't I'm pretty sure it would be easy t sort with an aluminium adaptor?
