Likely need to do the trace channel and tags before migrating the rest to be sure. Though it should work as is and others have done it the same way?
Regardless, if you already started on your own, I wouldn’t suggest migrating the template char over, it was never originally intended to be a base, but a set of examples. Its sooooo generic on interactions (overly so) because it lets people try just about anything with it. If I were to make a specific game however and knew my interactions and button layouts ahead of time, I wouldn’t use the template character for it, it has too much in it for most games and is overly complicated.
The basic GripObjectByInterface function run off of a trace or overlap lets you use all of the levers and dials and grippables as is. You would only need to handle per bone gripping if you wanted it and slot grip checks which is a self contained node (and AddSecondaryAttachment if you wanted two handed interactions).
I had/have plans on a very simplistic pawn just showing ground zero setup, but it keeps getting pushed back on my TODO.
