No, you'd need to extend the hub lugs. Plus have 15" wheels as well.

No your wheels are fine, you just need too drill the holes out and tap them as cossie hubs take bigger bolts than standard hubs

Are you sure they fit straight on? As you definitely need to move the lugs on the rear brakes to get Cosworth brakes on.
Normal Sierra disks are 240/260mm, 2WD cos are 283, so a fair difference.

You can just fit the cossie hubs to the rear. For the fronts the calipers bolt the other way round. Instead of the pad carrier being threaded like it is on a normal sierra you need to tap the hub for the 2wd calipers to bolt too.

Mondeo callers
St170 focus discs
Job done
Just need to drill the hole in the hub out
Simplest method to big brakes without the need to pay Cossie tax on the calipers (I've got some in t garage if you need dimensions and measurements if you have the heart set on the Cossie conversion, hubs as well, but don't forget you'll need the Cossie tcas as well)

You'll need cossie bearing carriers, or if you're good with a welder, you can modify the standard ones. You will also need 4x4 caliper carriers - they allow for the thicker discs - caliper is exactly the same.
