Why?  If we're buying Soyuz spacecraft from the Russians, 
it would make a lot more sense to buy the boosters also
and skip the integration problem.

Who is "we?"  If you mean NASA, I don't think so.  A space station
like you're talking about would be more of a construction project
than an R&D project.  NASA isn't set up to handle those.

(On the other hand, I don't think you need to limit your thinking
to small space stations.  If you're working with the Russians, why
not put an Energia third stage into orbit?  Convert it into a "wet"
lab, and you've got a habitable volume bigger than Freedom.)

However, we haven't man-rated the Atlas or Titan since the 60's.  
The current assembly lines for those vehicles are pretty much
booked already. You could expand them, of course, but the lead
time for a man-rated Atlas or Titan would be several years.
