No vex can not every simulate throne world's. According to lore the vex made a deal with crota because they wanted to understand the sword logic but couldn't and thought that visiting a throne world would provide some information into what and how to make one.
Problem is that the hive only have this ability because of the worm gods and the pacts with the worms. Prior to the hive being the hive they were a species of criten which originally ( as far as we know) didnt have these abilities. Only when they made pacts with the worms gods and became ascendant did they get this ability to create other dimensions. And even then only the strongest among them can do so like crota/ orix and also possibly nocris and sabathune.
By the by you could never force a hive to do anything because it defies the sword logic. Hive live or die in battle, the only way the worm inside them doesnt eat them alive is if they feed it the death of other beings so trying to hold a hive captive in either way would just kill it. Like if you manage to capture a high level hive like crota who has its own thrown room you would have to keep it alive some how through combat and if it failed at any point it would die and just regen in its thrown room.
Furthermore the vex dont need to force a race to serve them to make a vex army that vex are infinite and not just because they can time travel. According to lore around asher the vex radiolaria is more of a micro organism used to transform any organic tissues into vex tech which is why ashers arm is all metal. Vex will always exist because they can always build from other organic beings the army they need.
