For devices like phones and laptops, this sounds too complicated. Why not instead just use passwords, patterns, etc? I doubt anyone who's genuinely sensitive about their device being secure uses biometrics to unlock it anyway, so this seems to be just a convenience feature for the casual user with minimal security concerns. As such, making it more complicated doesn't seem worth it. And if we're talking about authenticating people in truly secure environments, my gut tells me that adding a couple more factors to even a simple fingerprint reader ought to be more secure and robust than making a super-complicated fingerprint reader and leaving it as the only factor.
