I think the original president would've rebuiilt the company immediately instead of sitting on his ass for two years.
You have to take into account that Rufus had Geostigma, and therefore probably couldn't restore his company, all the while keeping Jenovas head secret from Kadaj and co. I think that if president Shinra got Geostigma, he'd be using money everywhere to try and find a cure - but only for himself, and he'd probably sacrifice the head of Jenova to Kadaj if he lied and said he could cure Geostigma in a trade for the head.
