We could do it now but they will be substandard (larger and require more power) than fully designed packages. Integrated systems like a phone require a lot of optimization and part matching to optimize the size and power usage. To allow multiple part they would be larger and much more inefficient. The opposite of the selling point of most consumer electronic products. I actually looked into this a few years ago, phones no, but think game console might go this route if Sony, Microsoft, and Nintendo and smart. Anywhere where power consumption and size don't matter this can and should happen.
