The important issue, as to whether it can be done and look right, is how well does the forend fit the barrels now? I don't mean around the edges where you can see it. But, are the undersides of the barrels, the bottom half, a snug fit to the wood? All beavertails aren't. When you start removing wood at the upper edges you may find that there is an ugly gap between the new top profile line and the barrels. One way to tell how snugly it fits is to press a thin layer of Play-Doh inside the forend and slowly and carefully snap the forend into place on the gun. Then, remove it and see how much thickness you have in those areas.
That said, I was considering the same thing on my 200E 20 ga. I looked at it yesterday and preliminary indications are that it fits pretty well, and that it could be done to look right. Haven't decided to alter it yet though, because mine is a 99% gun and I kinda hate to alter it. My beavertail is not nearly as big as some, and I really shoot it well as is.
Good luck, Dave. Post pics before and after please.
