With a good DP and good post work it'll match fine. Don't forget that Hollywood mixes digital (high end arri, red, and low end DSLR and phantom, etc) with each other quite frequently.
If you want an easier job, go the DSLR route. I'd vote the 5D and 60D's. They'll match great with all the same settings, and the 5D being fullframe and thus "wider" it will give you some more options angle-wise. Plus, an extra camera never hurts haha.
