Well, we're talking about GOVERNMENT space standards. First, they have to let "design study" contracts to explore different alternatives for 6 months to a year. Then, they need to determine the best design and award the contract to a prime contractor, who then lets subcontracts in as many congressional districts as possible. They'll need to man-rate one or both of the EELVs and then perform a lot of tests. In the end, they'll spend about $10 billion and several years to develop a vehicle that can carry 1 more person than a Soyuz capsule.

If all we need is a simple, reliable vehicle to carry 4 people to and from the ISS (and serve as a lifeboat), the quickest and most cost effective concept would be to help the Russians increase the capacity of their Soyuz capsule. They've already developed more powerful versions of the SL-04 Soyuz booster. You could almost certainly increase the size of the Soyuz to hold 4 or 5 people for $100-200 million, and have it in service in a couple years, perhaps less.

But, of course, I'm talking about actually creating a cost effective solution rather than a new NASA program. How silly of me!
