Has anyone made a 2W ASIC that'll do those algorithms?
Not that I know of. I'm not very familiar with x11 but I have researched ethereum. From what I understand, the protocol is tightly controlled by a small group of developers, who could change the algorithm from POW to POS sometime in the summer, or whenever they want. 
Most don't understand the amount of time and money that goes into researching and developing an ASIC, but with most altcoins, it's just not worth the risk and effort.
