Collecting Characters

[SrG]

Currently you can only sell extra characters for gold, however in a future update we will be making duplicate characters much more worthwhile. So perhaps for your more valuable extras (4 and 5 stars, say) you might want to see if you can maintain enough space to keep them around.

Is this something that's coming in the near future?

Trying to decide if I should hang on to a bunch of ally duplicates or just evolve the main one I use.

We generally do not post ETAs for updates, all I can recommend is keeping an eye on the Game Updates forum.
