Hmm...this is an interesting concept. For the Unnamed Mercenary/Franz I think it'd really hinge on if he knew who was most important to him. I think he'd probably take the two wishes in return for the last wish, if he didn't know.
If the Unnamed Mercenary went about using the wishes, I think it'd happen as described in the spoiler block. Would the ends justify the means? It's hard to say. While he'd certainly have gotten what he wanted, maintaining that balance means taking it away from the very reason he wanted it back.
If confronted with the idea that a wish could hold such power, I think he'd turn it down, because at the end of the day, he wants to reclaim those things through his own efforts. Stealing them away would defeat the purpose for him.
