I can't imagine two weeks causing too much trouble. I've seen crap rewritten over and over on 6-month iterations that could make you weep. Just say the other guy's design is bad and you're going back to your own. If it's an "equally large task", obviously you're better off with a familiar code base. Suggest to the manager that he should not swap devs in and out of a project in time frames normally smaller than those used to ramp up new workers.
