Inherited a 2001 Trek 8000 MTB. Considering replacing the chainrings and crankarms for a conversion to Mid-Drive E-Bike. Would this be possible with a crank arm removal tool?

I am considering replacing the chainrings and crank arms even if I don't do a conversion to an ebike. However, I am considering a mid-drive conversion if the bike holds up. I know the general consensus is to only do so with disc brakes. The pads and brakes I have on this though have a lot of stopping power right now.

Would it be possible to do a replacement/conversion at home with a standard popup park tools stand and the wrench with the right crank arm remover/chainring remover?
