GRC wheel and Sprocket to fit GP3/4!

[Lee_Williams]

Thinking about drawing up a rear and front wheel hubs to fit a Polini GP3 or 4, I have 2 GRC RR's and brought a Polini GP3 4.2 for my son but obviously the wheels aren't interchangable, I thought about drawing up a hub that uses the GRC/PMT wheels and also uses the standard GRC/Talon/old Polini type wheels getting rid of the over priced new Polini sprockets, I know the Talon sprockets don't go below 56 teeth and the new reverse sprocket goes down to 45 so that could be a problem on the reverse, but it allows me to use the sprockets and wheels I have for the GP3 (Not reverse) 4.2.

Any thoughts or problems anybody could see?
