Nexus (2) is genuinely in good shape at the moment. Could be very close to ready for 1v1 map pool with some more tweaks.

Also, ive been saying this for years, a 4v4 map called Dust and Stones (COH1) should be remade for COH2, i started working on this project but have been very busy with RL. This would be a fantastic and sorely needed 3v3/4v4 map.
All this said it may be a bit late in the COH2 life cycle to be doing either of these things. The map pool has been in a moderate state for years now. On the other hand, if a skilled mapper has testers and free time it would be a good idea to remake Dust and Stones, and if Relic is willing to continue improving the map pool and add refined community maps like Nexus and Dust and Stones then why not go for it.
These would both be for ladder of course as I assume that is what we are talking about.
