Replacing Hunter Icore Dual 2-wire

My home has a way-overkill Hunter iCore 2 wire system with 15 stations. Is there any sensible way to replace the iCore with a Racchio, given my Hunter Dual 2-wire system?

@xns - Rachio is not compatible with a 2 wire system. I believe those systems use a proprietary signalling method to turn on a specific valve. One would have to replace the field wire (one wire per zone plus a common, instead of just two wires) and solenoids to use Rachio.
