Not going to happen. I'm not fond of new leader banters too, but your suggestion to go back to OBT features and stop near some middle-ground doesn't feel wholesome. From the outside this situation will look as if the studio still doesn't have an understanding of what they want to do with the game.
However it seems to me that 3d leaders can be gone as a hole in the future. Leaders doesn't seem to work as planned - i don't know statistics, but would assume that people are not excited about leader skins, so for now we've only seen one. Why would you keep a feature that don't seem to justify it's existence and only making development of a new leaders longer - card art, animated card art, 3d mesh, rig, animations, 2 skins.
And lots of people don't like new banters binded to leaders.
Before HC I imagined cosmetic items in new Gwent as some trinkets a player could buy or earn - both players sit at the table (or any other solid surface), playing cards, and can have something in the corner of their screen - a sword, beer mug, magic trinket, lute, jar with a trapped wisp, etc - all interactive to some extend. I would imagine this kind of approach to cosmetics be much more beneficial and popular as it provides diverse items for players to get.
