Tethered alternative?

[vcmystery]

So I'm not very tech savvy, but I had a dream odd as it sounds and woke up and thought I'd share my idea in the form of a question.
Would it be possible to have blackra1n run as an auto-executable on a device such as a thumbdrive, that has been fashioned with the iPhone usb jack, so that in the occurrence of a restart, and your without your laptop, you can use the device to boot your iPhone

[mockup]

I've wondered this too…
