Even if Rg does get bought out it's not like he couldnt reopen once things get better. He could start a truck or nationwde team like Harvick did and then work his way up with a new driver if he ever retires but dont think he will. RG will be like red farmer, racing in his 80's
Given his running Primm instead of Richmond. I would bet Robby would want to run it (if affiliated with Penske) even if they did not change the time. Remember Robby's biological clock is ticking and Indy is a young mans game as Robby has said in the past.
Even if Robby and RGM doesn't partner/merge/sell to Penske, I think Robby should pursue Roger as a mentor in some capacity.. could you think of someone better?
