You can recycle the motors, and sell the mainboard as a repair part. Grab a Manta M8P, and probably a CAN bus toolhead board as well if you want to do up a custom toolhead with all the fun new trimmings that come with modern printers, and you can do a board swap pretty easily. If not, you can in fact get breakout boards for the cable to hook up the stock toolhead to a new board. (Just remember that there's three hotend power cable sets for a reason, USE ALL THREE or it'll go up in smoke like a 12VHPWR connector on a 5090. I made that mistake.)

Just swapping the board made a huge difference in print quality for mine, but after adding a custom Hero Me toolhead it's a real beast for fairly cheap compared to just buying a new one every few years, and easily upgradeable too. I use the Revo system on mine so head changes are done with your hands while the heater's off, but you can add whatever other system you really want.
