Ditch the sockets ...
If you want to do something new, how about a completely water and dustproof device with no sockets at all? Massive bonus if you can autoclave it. Ok that's a bit of a challenge, but surely there's a a moderately big vertical market out there for sterilizable, hygenic computing devices?
And in design terms, sockets are ugly: almost as ugly as dust on the inside of the screen and the bill when you get your device a tiny bit damp. So, put the sockets and all the other cobblers on the wireless charging device, and it you get a full-fat docking station and a hermetically sealed device.
