Changing to different/smaller wheels on Maclaren

[SwellyBelly]

Hi - strange question, but thought I'd give it a go.

Does anyone know if its possible to use Maclaren Twin Triumph wheels on a Twin Techno? We have a twin techno which is fine for now, but as my twins get older and heavier, Id like to have a lighter buggy and as far as i can tell much of the weight of the twin techno comes from the wheels - hence would like to perhaps use triumph wheels instead.

Im sure there are are some issues with brakes, swivel locks etc., and with the warranty, but was wondering in principle....
