That’d definitely work as a scifi spoof episode
Like you suggested Summer gets to skinwalk some blade runner vat human, but while prank dating Morty she suddenly begins to really like spending time with him instead of always being annoyed at him. Probably because Morty is very nice around her when he doesn’t recognise her

At the end Rick explains that while putting her mind in a vat human its hormones didn’t suppress around family like her original body does, the vat human’s body doesn’t register Morty as a brother. Of course implied to be bullshit he said so she won’t stay upset about it
