Bad idea, better off buying a spare set of 20's (may be okay if going with the OEM staggered set).
Just know you'll be in for a rude awakening if you go to trade the car in to Tesla later. They deduct the full amount for new 22's since that is on the manufacture sticker and has to go to the next person. In addition, no reputable wheel/repair place will mount (20's) them back on your vehicle if something happens (say you have a flat and need to have a tire plugged).
As a caveat, I need to add that I went with a "square" set instead of the factory staggered, so I brought a lot of this nonsense on myself..
