Players in different positions

I think it's fair to say that a number of our existing, ageing players fall a little short of Pep's requirements and might well be gone in a veritable 'cull' next summer.
I just wonder though, rather than a wholesale avalanche of our players going whether, or not, any of them could be tried in new positions to try and re-invent themselves and stay with the Club.
i think we've had a sort of glimpse of this with Kolarov, but there are others; for instance, could Navas carve out a new career as an out and out full-back, or possibly as a wing-back ??
Could Fernando, similarly, move into the back line as a central defender, as well as Fernandhino doing the same.....and could the two of them make a successful partnership there ??
Could Zaba find a new (albeit short ??) lease of life by moving into midfield as a holding/defensive player there ??
.....and so on.
There could be other possibilities so what does anyone think ??
