Hi,
Most builders will be doing exactly that, mating a FWD Zetec engine from a mondeo to the seirra gearbox is really simple, job done.
A FWD gearbox also contains the diff so you would end up with outputs for 2 halfshafts rather than one output to send down a prop shaft to the rear diff so a no go I'm afraid.
Alternatively with some mods put the engine and gearbox from the FWD into the back of the roadster and have it as a mid engine car a bit like the atom.
