Yes, Cresteon should be cheaper here. Depending on how much existing gear can keep being used. Cresteon and Control 4 aren't THAT far off in pricing. I just can't see how replacing everything with a slightly cheaper solution will actually be cheaper than replaced a few things with a Crestron.

I would have said Pyng as well but not if you already have radio ra. Do you have your original programming code? Even though it likely wouldn't be used since you would be doing a major update to your UI's losing the old panels.
