You know there is an option to leave the Ctrl keys as they are on Qwerty? So when holding Ctrl, the other key you press is the one from Qwerty, regardless of your layout.
Or another option could be to use AHK to change the default Ctrl+ZXCV to anything you want.
Just saying, maybe if you really prefer Dvorak and that's the only thing stopping you, you can consider it. There are, of course problems with that solution as well…
One problem with mapping is that there is no way of doing it with my computer at work. There is Dvorak w/ cmd QWERTY on the mac, but I use a windows system at work. I've also mentioned that mapping is not an option as I'm not in the IT dept at work and any form of software would need permissions. One thing that made me fant to use Dvorak was that it came standard with Windows & mac both. But the flaw is that it did not have the easy shortcuts. Would be nice to have a mac at work too. LOL.
The best way is to have an identical layout in both places to make the transition easier. I've even resorted to using the same exact keyboards both at work and at home. This has made a massive difference. I'm guessing that it won't be long before I start to see the fruits of this.
