I understand the sentiment and applaud the idea of recognising the "team", however don't see that happening.
As to cooperation/collusion:
The Kenyans in particular use team tactics to devastating effect* in long distance running and there has been to date (to my knowledge) no sanctioning of such activity.
*notable exception; one particularly brilliant runner from Uganda, Moses Kipsiro, has upset the Kenyan apple cart on the Track at the 2010 Cwlth Games
Aside: my understanding of rules associated with pacing is that:
. No external (non-participant) pacemaking is allowed.
. However any participant in a race may pace any other athlete (provided such participant has not been excluded/lapped/disqualified...)
