Eh, noone has control over what gets stickied, so as far as I know you're free to try. I'm just giving an educated guess. The devs did go out of their way to stop the nonsense and give incentives to unlock stuff, that's true. I don't have a crstal ball to be able to tell you the offical stance on it, but based on the reactions towards tinker/transmuter scumming as a concept I'd guess they wouldn't be too thrilled.
Also, getting better and taking less preps into runs, doing quests and getting badges and working towards unlocking the flaming dungeons and the PQI is the truly optimal way of raking in cash. Money grind is a dead end in this game, allthough having the gloves available and picking up TT to mop up for gold from boons whenever you have him on board after a run is just plain nice.
I'd know, because I've done it a lot back in the day before they added all the aforementioned sources of cash.
