Well there's always the hope that Lakon will produce a multirole/cargo medium pad ship for the Alliance that is roughly the size and price range of the Federal Dropship but with more of a multirole/cargo focus. It wouldn't be fast (the Empire really has a monopoly on fast ships) but I think Lakon would be a good choice for manufacturer given that multirole/cargo ships are their main market, and it would probably be affordable, durable and have lots of cargo space for its size.
Unfortunately given that the only "content" we're likely to see over the next year will probably be some combination of invulnerable Thargoids and RNG-based weapons upgrades to allow us to fight the invulnerable Thargoids, I would say that the chances of seeing such a ship are close to zero.
It's funny you mention an imperial monopoly, considering they have no medium pad ship to compete with the python. The feds at least seemed to try with the dropship, even if they failed miserably.
