I am already thinking about DLCs…. is it too soon?
Well, my answer would be yes.
From my point of view, as the game is not released yet the devs are surely working like crazy to deliver it on time, and for now they probably do not have the actual time to think about what to add/implement after the release.
Talking about your ideas or what you would like to see in the game is always good, so maybe it is too soon for DLCs, but that should not keep you from suggesting stuff you think would work! :D
