Wow, congrats. An original idea. Don't think I've heard this one before.
Not very Trek
-like - because no Fed prison could be hard-core enough to be interesting - but as a concept, sci-fi Oz
or Prison Break
...not too bad.
For all the alien-on-alien shower scenes of course.
That was my first thought, I have to admit - taking the highly-imaginative vicious insanity of Oz
and placing it in a sci fi context would result in a quantum increase of the imagination quotient. Might be hard to stomach, or just flat-out confusing to hew-mons, but it would be...different.
