Welcome to the forum. I am just thinking out loud, no experience with this lift, but I would try a thin rubberized weather strip. I think, using smallish diameter bits will be fine. But using a large bit, like a panel raising bit, puts a lot of torque on the router. The only way to find out would be to try it on some scrap. Go slow and if the router turns in the lift you will have to find another solution. Again this is what I would do. If you are not comfortable with any of this do not do it.
