Not going to happen... destroys the purpose of indestructibility and weatherproofing.
If you have the swivel open and you drop the DSLR, its going to break.
Too many creases between the swivel parts that make it less waterproof.
If you like swivel screen so much stick with the 70D.
As someone who has a 60D with 70,000 shots on it, and who takes the camera hiking and canoeing (not a pampered life), let me make a few comments about tilt-swivel screens....
Waterproofing - the 60D, with a tilt-swivel screen, is surprisingly well sealed. According to canon, the level of sealing is supposed to be the same as a 5D3, not as good as a 1Dx or 7D, but better than a 6D or the rebels.... You do not have to make the joints on a tilt-swivel mechanism waterproof, just the ends....
Protection - turn the screen around and it is protected from scratches... Mine is still scratch free, something which can not be said for my friends 5D2.... And her camera is less used than mine and has seen more gentle use.
Fragility - my local camera store says that they have seen more DSLR's with broken fixed screens than articulated screens (all manufacturers, not just Canon).... Perhaps it is because the "lower end" cameras get tossed instead if being fixed, but however you look at it, it is not a slam-dunk....perhaps transportation of a camera is more dangerous than usage of the camera?
