I don't remember from your earlier posts what your skill set is.

Frame failure can be catastrophic. If you're comfortable with your skills and you have (or are willing to buy) the appropriate tools, then why not? If you haven't done this kind of thing before, I might think twice.

It's not that I'm opposed to the idea in general. I'm totally comfortable working on my motorcycle - a mistake there could mean I die or worse, just like frame failure on a bici. I learned the skills under the supervision of my DH, a trained mechanic. He still checks my work when it's something I haven't done often, like bleeding brakes or valve adjustments.

It's all in what you know how to do, and in what you want to do. It sounds like it would be a really cool project.
