In "Inside Man" a way is established where the Federation have direct contact with Voyager. Now it is established that nothing living can go through this hole in space or whatever it was but why is it that the Federation did not take the opportunity to send stuff to Voyager. Perhaps they could send a couple hundred quantum torpedoes or other upgrades that Voyager could use or even a brand new Starship. Voyager admittedly was quite a new star ship in itself but if Star fleet for instance sent them a Defiant class starship as well then it would make Voyager a lot safer as they would have almost twice the firepower. It was mentioned that Voyager could be run with 100 crew and we know a Defiant class ship can run with around 40 or 50 so it could have been done. Or perhaps Star Fleet could have sent them a Prometheus class star ship as that looked like it did not need a big crew to properly operate.
Is there a plot point I am forgetting which would make this impossible and if it was possible how would the show have changed if there were suddenly 2 Federation starships?
