Interesting. I've wondering about that with Huck Norris and TT. I have a tubolito as my spare so it will likely fit into the Tannus, but without inflating the entire tire. I'm quite sure it's too stiff to allow the tube to expand very much, but in that situation it could be like having Cushcore in there with a flat. Time to give that a try.
I've also thought it would be great to have a minimalist tube - like Tubolito - that could deploy from a cavity inside an insert in the event of a puncture. There are several hurdles here, and one is keep the tube puncture free until you need it, not to mention how you'd add air. A dual-delivery valve like the one used by Schwalbe for ProCore might work but those aren't trouble-free.
I love the idea of getting a flat, flipping a switch and then having a tubed system to get you out without any repair needed, without having the weight get out of hand. It may be a pipe dream but more challenging problems have been solved in this industry.
Eventually you'll likely be able to do it with a wireless system and a button from your bar. Or maybe with a glance of your eyeball when the heads up display on your eyewear indicates a flat!
