Mmmm thick traces. Yes, this has been done in a variety of ways, both making masks and printing directly on the copper. It's not a great technique, but fun to try if you have the stuff on hand. If you want to seriously etch PCBs at home, a resin printer is phenomenal for exposing boards controllably and at a high resolution with great ease.
