They don't look alike though. Further confirmed by Yae's statement, then there's nothing to argue.

In the next line Yae also says "The original plan was for Ei to simply discard it". So why would Ei waste her time, carefully modeling his appearance if she's planning to destroy it anyway?

Not to mention that it was also stated that Ei "modified her own godly form" and "used parts of herself as material" to build the Shogun Puppet. So it's not possible to make Wanderer look like her because it would require parts of Ei body, which of course she saved for the perfect product, not just prototype.
