Bell goes without saying, he would have just 'got it' on Pep's first day so should really be left out of discussion to make it fair. Several of the 60s team would do it, no problem. Mike Doyle could easily replace any of the cbs. From the 70s Barnes (with Pep's work ethic), Tueart, would be superb.
But one guy who could be perfect for Pep & play a bunch of positions: Brian Kidd.
