No, the Atlas that is proposed to be man-rated is the 401 varient, with
just one core engine, a single centaur, and no solids. See

where this is very explicit. This is because this is the simplest
configuration, with the least to go wrong, and has the most experience
That document was very interesting reading. It is intersting to see how
LM is
using the fruits of old cancelled projects to evaluate the Atlas 5.
I found one glowing problem area: that of crew ingress and egress. They
assert that in an emergency using the pad abort system to launch the
capsule
away from the rocket is a better approach than exiting the capsule.
Yes, except ... in the case of a capsule fire.
Did you see the recent article that showed a proposed roller coaster type
escape system for CEV? I have a feeling that just about any new emergency
egress system planned for Ares I/CEV could also be implemented for Atlas/CEV
for a similar cost. In other words, NASA's got to pay for that system no
matter what the launcher.
