Cyberpunk Rules

Genesis P-Orridge of seminal industrial group Throbbing Gristle did something similar:

[P-Orridge] married Jacqueline Breyer, later known as Lady Jaye, in 1995, and together they embarked on the Pandrogeny Project, an attempt to unite as a "pandrogyne", or single entity, through the use of surgical body modification to physically resemble one another. P-Orridge continued with this project of body modification after Lady Jaye's 2007 death.
