Doing this is totally up to you, but I wouldn't recommend it for a few reasons. Firstly, of course, you would void any warranty. Also, the intrinsic value of either instrument would be void--so if you encountered problems in the process or somewhere down the line, you would be left with no options. Also, you could run into various problems such as intonation, warp, etc.
My 2 cents.
All the best and happy new year,
