Sovereign can do St. Johns, Las Vegas with a tech stop out of LCY. 60XR's and premier 1's are probably the only "white tail" biz jets you can buy right now without a 24month wait.
No point having a good idea and then waiting 3 years for the equipment, theres been more 680's delivered since mid 2004 than 750's since 1998 so I thinks you're quite right that Cessna aren't going to play ball on anything.
Maybe a bit of pressure put upon them from NetJets perhaps
