I am obviously not Jeff Bezos but I asked myself the same question.

Could such an extreme outsourcing service (not necessarily only fabricating chips) paired with the accessibility of AWS be viable? Does such a company exist?

To some extent, yes, and a few of those companies already exist, with names like Xilinx and Altera. Their FPGA products are available at 22 nm now. But they're not of much use when it comes to selling cheap commodity hardware in volume, of course.
