I do too, but there are two levels to a redesign:
1. All the current models, no new ones, and as close to the WD Dex as possible
2. Wish listing it/total new real codex design with new models possibly added etc.
Either way, it is hard to decide on some army-wide concept rules that define the army, make them fun to play, different than other current armies, still allow different builds within the army, etc.
Seems like that is the first step to me anyway.
I'm shooting for a number #2 myself, working on something comprehensive/fair to submit in for them to use (well, maybe...they don't have to use any of my suggestions. I just want to offer something that I'd play AND would be willing to have played against me).
