Nope, we've been down this road before, and no.Sometimes. But not always. Especially given the freedoms the other shows got.
9 players, hmm?MASH had a smaller main cast than Voyager, it's inherently easier to tell a story when you have a smaller cast.
VOY would've been better off with the Central Cast just being Janeway, Chakotay, Tuvok, Paris and the Doctor.
Kim, Kes, Neelix and Torres should've been Secondaries who didn't need to be seen all the time or be in every episode.
M*A*S*H had Hawkeye, BJ, Winchester, Colonel Potter, Radar, Klinger, Margaret, Father Mulcahy as their ensemble, so only one short of VOY. They also introduced Sydney, Igor, Rizzo, Zale, Nurse Kelly, Nurse Baker, Colonel Flagg, General Clayton, and numerous others who made more than one shot appearances, and actually got character development.
It can be done.
