Just thinking out loud now..... if the carbon tubing has a "Known" stiffness of less than the original steel tubes, could you not insert a smaller diameter crabon tube into the ones you have, this would stiffen things up, possibly add a bit more weight over the steel tube, but doable.
While possibly a scary thread ending in self harm, i applaud the forward thinking and Adapt and Improvise and Overcome thinking to the problem of fucked frame tubes :)
Cats on smack, rad and dangerous :)
