Base and units unlocks

So I was thinking that maybe you could be rewarded a sort of base or unit skin if you complete a certain objective or game. The skins would just change the look of the unit or base slightly, like say making the locust have a different armor plating, decals on its model, etc. Or say having a base with certain symbols on it that you could attach anywhere. This is just an idea I had, and I don’t think it should be implemented as of now. The team has a lot more important things to work on right now like balancing and new leaders. Maybe in the future when the team is running out of ideas they could implement this for more customization? I would love to hear others opinions on this idea and maybe ways to improve it.
