I'd say change the CK20 to the CK25 with all its extras included makes more sense than having the CK25/30 the same size.
The LB1914 could be the 20 HP model with optional HST or Shuttle shift, the CK25 in the CK20 package, then the larger CK30 all with Synchro shuttle or HST.
I agree that all the models should be available in HST or shuttle.
While I love my CK20HST, I agree with getut (in other posts) and some others like Bob Shurka, that it would be the cat's meow with the 25HP package, telescoping arms etc.
All the models should be sloped hooded and loaders with curved arms in my opinion.
The website is supposed to be revamped, and parts support is something that has been suggested. I'm hoping to also see information about past models available also, if nothing else, at least the specs and years of MFG.
I could think of lots more things, but then so could everyone else probably. Make too many changes, and they'll cost way too much!
