Only issue you'll face is that you'll need special couplers for them.
The European Sanke's require a longer probe. Part of me thinks you could order extra probes and just switch them out as needed though if you want to use an US sanke.
I'd be all over it personally since my setup uses sanke's exclusively(with the option to run a soda keg if it ever shows up, per my sig). But you'll need to think about size consideration in your keezer/kegerator. Also, the coupler's run ~$30, so you'll need those + fittings.
What you are gaining is the perfect keg for a 10-12 gallon batch.
I'd go for it if you can make the setup work.
