Basically there’s 2 possible outcomes. One is that it turns out you have good footwork anyway, and you can pretty much just get on with it- there’s no extra skill needed, if you’re riding well on SPDs you shouldn’t have much of a learning curve
The other is it turns out that your SPDs are a crutch for you, and you depend on them to stay attached to the bike. This is way harder because you’ll basically have to relearn some basic stuff and it can feel pretty undermining and frustrating. But at the end of the day you’ve found a weakness and fixed it so even if you go back to SPDs you can take that back with you
(or actually, there’s option C, which is that it turns out that they’re a crutch, and you just don’t care, and carry on as you are, and just use the hardware fix for the software problem. It’s not ideal, because there’s still things you miss but it gets the job done)
