Default 1.7 Puma Engine?

My Focus is a 1.6 Sigma.
Now I won't be doing this any time soon but it's nice to know different routes I could go down etc.
Now my Focus engines a little worn, it's done 70k of Start/Stop driving, burning a little oil but it pulls well. Next month it will be having a full servive
including timing and fan belt, waterpumps, tensioners etc. So the engine will be ok for a good while I think anyway.
Now I'm wondering how easy a 1.7 engine would drop in?
Now it's a common conversion with the Mk5 Fiesta ZS but I think there engines aren't as complicated as the Focuses. For instance the Focus has a air flow meter in the intake manifold and the fiesta has none.
I assume everything would bolt straight up including the 1.6 fly, box and clutch being the fact their the same engine
I'd be ok swaping the engines over, it's the wiring I would be stumped with.
Anyone know if this has been done on a Focus before? or how easy it would be?
Thanks, Bailes.
