"You call yourself a middle-distance runner when you've run a mile in under four minutes, " Moorcroft, now chief executive of UK Athletics, told BBC Sport.
Caborn, Jowell, Carter and UK Athletics chief executive David Moorcroft will meet IAAF president Lamine Diack on Friday to try to persuade him to accept the new plan.
He backed Moorcroft's view that there was no evidence Dr Arbeit would advocate drug use for Lewis, and said Jonathan Edwards had also given his appointment his blessing.
Despite the fact that the world record has come down considerably - El Guerrouj's mark is three minutes 43.13 seconds - Moorcroft believes it is still an important part of training.
Dave Moorcroft's time of 13 minutes 00.41 seconds - a world record at the time - has stood since July 1982 and Farah knows breaking 13 minutes is the least he needs to do to be a medal contender at next month's World Championships in Berlin.
