Probably, but we want to simplify this. Actually, on our roadmap we are planning to replicate the user's data on multiple clouds so that the process of selecting the "correct" file (untampered) is automated. The main difference brought from the technology we use is that while a system like the one you describe involves some probabilistic decision-making (like voting: e.g. out of 3 replicas, you choose 2 that seem correct) we have a mathematical way of verifying the integrity of the data (so you don't need to access all replicas to be sure that you are working with the correct data).
