I think because of SE being Installed I think things like Cargo / Sat Launches would be a good stats to grab. I'm not sure if there is other simple none taxing stats to tap in with some basic totals of something. Like Research Done, Biters Killed, Etc. That being said you don't want it too bloated and you don't want to tap into stuff that causes a lot of calculations either. The total Cargo / Sats are built into the Info interface already per player so those should have code samples there.
The New Surface is not really a big deal anyways. It's just more if you create a Vanilla surface outside of SE method as far as I know it's not a place a player can visit from the space charts.
I like the idea of the list / status UI especially if it's using something more of the new interface. The old style that people use to do is too ugly now haha.
Hope you figure out the Evo issues. I know that is the big goal of the mod itself. I will prob look into running it later on with K2 + SE.
