I'd say not practical, there's more to it than just the control console. There are ducts, control modules etc. And great expense.

No parking sensors on the LX.

Best maybe to ask Ford dealer about fitting them, may be an easier job.

Why not buy a zetec in the first place?

For myself, I prefer the LX. It has a temperature gauge on the dash and the AC, fans etc seem to give me more direct control, but that's me. Less to go wrong too.
Same with windscreen wipers, I prefer to do it myself.
