I don't think that we are there yet. When someone actually tries to match the performance of glow with electrics, for more than just a brief moment of full trust, they still have problems. For instance there has been some local effort to match Q500 performance using electrics and it turns out very expensive and heavy...
I the box of an ARF says that it will weight 20oz on electrics and he gets 30oz using glow I would really like to see the actual numbers...
There are lots of weight savings that can be done and has already been mentioned in this thread, I haven't see any comments on that though.
There's nothing left to remove. The landing gear is gone and the carbon pushrods weigh 7 grams. The engine weighs 6.6 oz. If I add structure it will just result in more weight.
