I was tossing around the idea of making a bait that would possibly target Mink but also take coon and otter a 50/50 muskrat and crawdad base and a little beaver castor would it be worth a shot or is there something better

I used salted bullheads, would catch otters in pocket sets for mink, not too often worked well for mink on a 220/160 impaled the fish and set in/under water. The salt toughened the fish so they wouldn't "melt/spoil", Kurt and I netted a lot of small fish that we couldn't sell live so we salted them and found a use for 'em!
