I doubt a Dremel is sufficient, but you can try. The bracket is very tough, so if a Dremel works it will take you long time and use several cutting wheels. If you decide to go this way you can PM me. There are some wathpoints and hints, and I will be glad to help. And while you are at it, why not order and fit BRBs? Cheap, easy to fit and absolutely a noticeable effect. I have a hint here too..
