Another thing, is that I could simply drill two new holes in the mount I have, as far forward as possible. That way the base plate is still secured by all four screws and that would move the scope rearward...hopefully enough. Obviously about an inch would be lacking contact on the base plate, but I think there would be enough contact for it to hold properly. The holes in the mount are not tapped, so it would make for a much easier job. All I need to find is a drill press.

Does this seem doable to anyone else?
