I don't know if this is the right place for this, but it was the best place I could come up with.

Is it possible to remove the filler from lug work on an old steel road bike, then to cut down the tubing to a shorter predetermined length and then rejoin the frame with the same lugs and tubes with fresh filler? Will I have to change the geometry?

I also understand this is fairly silly and a lot of you wouldn't bother, but I have a frame hanging that's just too large for me and has minimal capital into it as well as not being a great looker so not exactly a tradeable either.
