I think it would be a neat idea if, for every ship you purchase in the C-Store, you also get a holo emitter of that ship's image that can be equipped on other ships.
Let's say you purchased the NX-class replica Light Escort in the Enterprise bundle, for instance. It's a cool ship, we heart it. But it's only got 3 weapon slots and is therefore only really fun for a vanity ship or for a new character.
But if we also got a holo emitter device, like those purchasable with gold-pressed latinum, that projected an image of the NX-class, we could also then enjoy our purchase every once in a while on our higher tier ships.
Love the idea. I imagine for fairness though, they'd have to automatically shut down in PvP, and then you reactivate it on leaving the PvP instance (I say that as someone who's barely touched PvP though).
I did just learn that current holo emitters are consumable items, which I actually didn't realize.
But I think if these were permanent items, given a cool down period, were disabled in PVP maps, and took up a device slot, it would be a fair enough item to receive for the money one pays for a ship from the C-Store.
