But EK205 isn't (well it might be EK206 since 205 is the DXB-MXP service).
OP would arrive from Zurich on an Embraer which, 99.9% of times, will land on a remote stand. He will then take a bus, which normally takes him to the arrivals area in MXP Schengen. It's been yonks since I've transferred Schengen to non-Schengen in MXP, and I don't recall a transfer corridor from the downstairs gates.

Worst case scenario, the OP would have to land, get through the baggage area, then go back upstairs, clear security, go through the duty free, through passport control, head over to Satellite C (Gates 50-onwards) where EK usually leaves from.

Best case scenario OP lands, finds a (usually very quiet) transfer checkpoint, goes through security, through passport control, head to Satellite C and depart.

Best case is about 3/400 metres shorter in terms of walking. Sure, it can be done in minutes, but... I wouldn't risk it. Personally.
