I think WGT has said they will not transform any of the CTTH courses into full stroke play courses. I think you can search the forums.
I've played Wolf Creek IRL and really thought it was a fun course. I got to play the Pebble Beach courses (Pebble, Spyglass, Spanish Bay, and Poppy Hills) and Pebble is obviously an iconic course, which would be nice to have (and seems to appear in every golf game ever made).
Bandon Dunes is now #1 on my list of places to play, after I got to play Arcadia Bluffs in MI. Whistling Straits would be fun too.
As far as new courses, I honestly would play anything. But just for my own personal preference, I would like to see more tree-lined courses, as opposed to wide open ones. Something like Sahalee, Olympia Fields, or something like that. I'm sure if WGT is operating in 2019, we'll get a nice list of Open courses :)
