Default Flash SM-605V ROM on SM-605?

I realise this is probably a terrible idea, but since the Verizon version of our tablet has Kitkat now, what are the chances that it will work on the rest-of-world LTE edition (SM-605)?

I believe the only difference is the LTE bands that it supports. I don't even have a sim in my device, and I use Wifi exclusively, so if the worst that could happen is that I lose mobile data, I think I'd be willing to risk it.
