Yeah, some of those 3rd party outfits I mentioned previously can do exactly that. They have ways to get root access and do all sorts of things. I know one in particular will sell larger packs to people and even has a handy spreadsheet of what each model will cost based on the battery that's in them. People are even able to pay a little extra to make non Performance cars performance models and other crazy upgrades that Tesla said would be available "someday" many years ago. Of course this voids your warranty but if you have a car that needs a $15k pack and it's already out of warranty... options like this are incredible. Lots of happy people who had an early (2012, 2013) 60kWh car that paid for a 85kWh pack and the air suspension required to carry it. Newer cars have the proper suspension and other things in place already but it's still nice to be able to do those things even if they aren't sanctioned by Tesla.
