First off. that ship get's damaged? No Star fleet parts, so let's find some alien allies to help. After awhile, Voyager would look much different.
Voyager get's assimilated. Minimal repairs. The aria still retains a Borg look.
Be less PC. Go out to the limits, address real issues facing society.
USE MODELS! The CGI in Voyager looked terrible, today, I'd still use models, they just look sooooo much better
Introduce plots that would have aliens join the crew
any other ideas?
