Spoken as only one that's never attempted to weld something this thin before could do. Most welds in stuff this thin, including bike frames, use socket welds. That's a whole lot different than trying to butt weld something 2-4mm thick.
Your chances of getting back the "original feel" are virtually nil. When welding stuff this thin, it's darn near impossible to achieve the original strength. It's just too easy to burn through, and without proper penetration, the strength will suffer. Generally speaking, a backing ring is used for welding thin pipe sections. While the weight would be minor, it would also be at about the farthest point it could be from the center of gravity. Minor, but enough to change the natural trajectory. Sure, you could weight the opposite end with a couple of ounces to compensate, but then you're upping the overall weight even more.
As 8-ball has also indicated, material properties are dictated by both composition and rate of cooling. Even if you could get a decent weld, ambient air cooling may or may not be what you want.
You've nothing to lose by trying (unless it costs you $$$), but I would not get my hopes up too high.
