Or "I saw that some cheap rims just have very rough grooves along the braking surface and those might be what's making it so hard to work the tire on. Maybe you just need to knock those down a little bit on the side".
The answer to your question from all responders is obviously "No, we have not tried sanding down rims." That tells you something about the wisdom of your idea.
You want to dictate the terms of a "helpful response" -- and then ignore (and complain about) any and all other responses
from people who are trying to help you.
Nice.
