Much better, and doable - there are Ford Focus like that. I have only rallycross Focus photos around if you want but I've seen ones of a a street car. You need parts of floor pan swapped, custom made WCR-like rear suspension in Focus, stronger front and coilovers or something to set it up. gearbox, diffs and everything can be adapted from Sapth. But most of all you need creative mechanic with welder and lots of ideas
