Well, the 318 has been reliable for quite some time. Complexity of the newer ones may make the cost rise quickly, as well as the size. It does seem a bit bulkier than, say, a Mustang 4.6L we've seen done here.
I think it's not impossible, but it's just not been done as much. People use Chevy engines for ease and availability, and Ford because, well, these are Mazdas.
