Though the hose clamp might be able to stretch?

I'm seriously considering giving this a go since I have nothing to lose and everything to gain. This seems like it might have a small chance of working..

it does stretch but it won adapt to a teardrop like shape of your seattube snug enough to offer a secure grip.
You can either glue it in and tighten whats left of the collar hoping for the best, or, what I would do, chop off the top of the collar, chop off the rear of it to make it as similiar to a round shape as possible, and then think of hose clamp or maybe a seatcollar even if you're accurate and a bit lucky to tighten the whole thing.
I am a bit of a mad sciencist type guy, but pretty sure it can work the way I described if done properly.
