It's something we think would be great but it's not a priority right now. It likely would need a pretty hefty development time to make this happen and we'd like to focus on the gameplay things first, like improving the RPG, Recalibration, fixing the "Inventory Manager" game and such.
We'll mention the transmogrification and full re-customization of agents to the team again though, in case some opportunities open up to get these things in.
