Peasent to Princess

I have two ideas for this particular scenario

Scenario 1: A medieval princess discovers a young male peasant has a strong resemblance to her. So she gets an idea to get out of an arranged marriage, transforming the boy into herself for the wedding and the honeymoon.

Scenario 2: A prince is **** to choose a princess to be his bride, but not wanting his parents to learn his sexuality, he has a young feminine looking peasant boy to be his new bride (after a few 'princess' lessons and adjustments)
