Hypothesis: the Wizard is an illusionist wizard. He has Malleable Illusions as a subclass features.
"Starting at 6th level, when you cast an illusion spell that has a duration of 1 minute or longer, you can use your action to change the nature of that illusion (using the spell's normal parameters for the illusion), provided that you can see the illusion. "
Since the simulacrum is an illusion, and lasts longer than one minute, I'd say you (and any duplicate) could change the nature of the simulacrum within the spell normal parameter as a single action.
So once you have slept and recovered all your spell slots, you command your clone army to change to simulacrum to "you in your current state". So with full spell slots.
(of course, I'd balk at my players doing this, this is just a tought experiment)
