For a few crowns or a bit of Energy you can change between gates at the start of tier 2 and 3 (means at Emberlight too), either to avoid unwanted levels or to chain together your perfect run to the core.
It doesnt need to have anything fancy nor does Emberlight need to have its own station, maybe npcs or vending machines somewhere.
The station at moorcroft's has those convinient marked areas on the floor too.
Maybe if you do a boss on every tier you could get a nice reward at the end.
So are you saying you want to switch to another gate? Because you can already do that for free.
If you're saying change stratums within a gate (presumably only for your party), then maybe...? It should probably operate similar to old gate building (minus getting crowns for minerals) instead of giving up some crowns or energy.
