I say go for it! I upgraded my inexpensive fat bike to 1X and it was well worth it. 12 speed will not fit the hub, nor will sram 11 speed, but shimano 11 speed will fit. For an affordable wide range cassette get a sunrace 11-46. If you want to go 11-50 you will also need the wolf tooth goat link to allow the shimano derailleur to work. Just about any 11 speed chain will work. Any brand 1X crank/chainring will be fine too. Or you could look at one of the other drivetrain companies like Box. They seem cool but I have no experience with them. Sounds like you are probably going to have a shop do the install so just make sure to check compatibility of everything with them when ordering your parts. Good luck!
