How about replacing the Workman layout with Colemak-DH (either my DbgHk or stevep's DvbgHm; see the Colemak forums)? These layouts are solutions to the issues that created Workman, but within the Colemak universe so they'd be nice for your device which is already quite Colemak oriented! :-)
The only issue that needs resolving is how to handle ISO (simple) vs ANSI (more of a choice) keyboards. If you go for one of the DH mods, there's room for one of each... but then, Dvorak would have to go which may be overmuch.
