It could be done, I only reservation would be that the lines of the Flyte are just so "right" that I think any slight deviation from the curve would show. The forks would be quite a mission to copy as they have hollow, tappered, curved tubes! I have done mock ups on the computer of a ladies version of a Flyte, with the curved tube replacing the top rail. I have the curve of the new tube mirroring the rear frame curve upside down and to be honest it looks to me like it was supposed to be like that. Much better than I was expecting it to look. I may not do it, if the other Flyte deal comes together. I have not decided yet.
