I've run a 700c rear wheel with a 26" front wheel on a bike designed for 27x3/4" wheels, and I don't think it changed the handling of the bike at all, I can certainly still ride it just as easily. What the OP is attempting/has done is far less drastic, as the overall diameter of 700c wheels with relatively narrow tyres is probably quite similar to the outside diameter of the balloon tyres on whatever sized wheels the bike would have come with.
