Open Wheel unification can be achieved by getting Conquest and Haas to leave Champ Car. They don't have to join the Indy Car Series, but it would help.
If they were to join Indy Car, that would essentially leave GF as the nowhere man. KK being new, does not have roots in the sport that can be tied to the PPG Indy Car Series.
Get those teams to join and then pile on the press about the end of the split. Because GF being the lone team owner holding out can't be seen as an elemet of a split, not if the information is presented to sposors and the pubilc.
One series is closer than you think. I say get it done!!
