Sure.

Sure. OTOH, if someone wanted to support the following usecase, they
could provide a script that does it all:
1. I have a Tails USB stick installed with isohybrid+dd, that I'm
not sure about.
2. I have a Tails ISO that I believe to be genuine.
3. I want to check that what's on the USB stick matches this ISO.
However, reinstalling from the genuine ISO is probably simpler in
most cases.
