Not that I know of. The WP kit required you to hack the crap out of your harness and change the key over to a different style that most people that did it, need a new harness. That is really the driver of the cost if having to re-run a new backbone harness. But the good thing is today you have 3/4 real options. The BDM RIP (get the full harness version), get a new factory harness from Donna/Eric and then get an Axel's EHC, or get a DOC. The last option is get the Thunderheart parts and do it yourself. There are other options if you want to go HD controls but I like the look of the BDM controls so I am keeping them. BTW you still will need to get an original key tumbler.
