Yep gotta fix that gun .I like the spring idea .How hard is the bolt stop to take apart ?
It's extremely easy to take apart. You pull the retainer screw out and it separates pretty easily from the receiver. When you put it back together, it will be a litter harder since it will now be spring loaded. I'm assuming your leaf spring is broken right off of the ejector.
You can see the screw you need to take out in this picture. It's the one that looks like the end of an icepick sticking out of the bottom of the ejector/bolt stop housing:
