140KIAS, I think Glasgow are helpful whenever they can be, but I think you're asking a bit much, IMO, as you're a bit close to the climbout/final approach (depending on runway in use). East Kilbride-Stewarton-West Kilbride might be ok though. At that time of day, I'd ensure I file a flightplan so the controller has details when will help ensure success through involving less work for the controller.
Be interested to see how it goes. Have a good trip
