I don’t think the radiation should be too big of a problem, they are in a very low earth orbit, well inside of the Earth’s magnetosphere. Not to say there are no health risks, they lose a lot of bone and muscle mass, but radiation shouldn’t be a big concern

Noo, Joker! Don’t implicitly assume the continuum hypothesis!

It’s not so weird, and if someone wants to take the extra risk with their own payload (and get a discount on the launch, i imagine) i see no problems with it.
