A Walk Cycle for Antonia?

I noticed that there were a pair of shoes for Antonia on the Antonia's Free Stuff site. It got me thinking (not for the first time) that one thing Antonia is lacking is a Walk Cycle. I remember trying to make a walk cycle for one version of the Victoria, without any success. I'm wondering if I am masochistic enough to try it again with Antonia. If anyone has any insights into the arcane world of walk cycles, and the best way to create them, please speak up.
