just wondering if anyone has challenged this idea?

i'll be getting a mc28 soon, but laws state in canada, a vehicle that imported into canada that is newer then 15 years can NOT be insured. however if a vehicle is atleast 15 years old, which a 1990 mc21 is, can be insured.

SO...would someone know how easy it is to swap forks, rear swing arm, engine, instrament cluster into the mc21 frame?
