the maker,
Having used inserts for a long time and having finger that swell and shrink as I bowl, I have used lots of implements, tape and shims.
I understand why you used the scene to portray how easy it is to use, but I disagree most strenuously with the concept of putting tape inside a vinyl/silicone insert. It is far too easy for the tape to slip inside the insert or for the bowler to push the tape out of position because most tape glue sticks very poorly to soft inserts. Once they start sliding around, the glue gets all over the bowler's fingers, messing up everything. I think it is bad idea to even show this as an option. Too many people will try this without giving it a second thought, solely because they saw it.
To reduce the size of inserts, shims are an infinitely safer and better idea in the long and the short run. You can probably use your tool, where I use a small slotted screwdriver. That is probably just fine. It might even work better. The price certainly makes it worth the test trial, to say the least.
Maybe you could just show inserting tape into a small woman's ring finger hole that doesn't have an insert.
