This is a really rad idea, I saw those videos a couple years ago and wanted to develop my own factory but never got around to it. I think what you're doing is a better way. Those massive factories are designed to make just one design but by using a more universal design the output possibilities are endless. I don't know how feasible it is but I think developing something similar to an industrial robot would be the best way to accomplish the task. As with any engineering task you're only limited by imagination!
