Internal sleeves is how i fixed my personal bike/frame that came off my roof rack going down the highway and badly dented the top tube. I made the sleeves on my lathe (each end had a different requirement) and brazed them in one at a time. This method worked great and I am surprised it isn't more commonly done (especially on brass brazed and pinned classic frames). I choose not to replace the through the top tube brake cable routing. I had a Hellenic seat stay attachment where the seat stays pass the seat tube and attach under the top tube so there was no way to just replace the entire tube tube.
