Link to mastodon mod here, looks like it doesn’t take standard hobby-grade motors so you’d need to get creative. Stock motor replacements for burnouts don’t usually exist, so you’ll need, at a minimum, to replace both flywheel motors, rewire with new switches, and get a power pack properly sized for the motors you’re using (likely a 3s LiPo with around 1500 mAh capacity and 40c).
Yeah, it would be bad to sacrifice crisp feedback. There might be a way to do it using some roller bearing, but that's probably getting away from where you want to be.
If you're interested in experimenting, I've drawn up a slide catch. The current catch release is great - so great I basically don't even feel it. The downside is that the catch is unrestrained so the trigger is free to move away from the release. A slide catch might or might not release as cleanly, but it's got restraint built-in.
