Urg, don't. While it's close enough to his normal environs that I'm sure he could cope, and perhaps even do well, given that he'd be considered an Ace, it's really too gritty IMO.
I don't expect Doug would be immune against some of the more annoying jerks in that world, such as (depending on when he arrived) Demise, the Jumpers, the Astronomer, Puppetman, etc. And that could ruin his whole day.
Plus of course, since he never caught the wild card, there'd be the risk that he might get infected with it (particularly if he ran into Croyd Crenson that one time he became infectious).
