Wow, with all the samey relationship threads and moral dilemmas, it's great to see something original.
I'm not sure I understand the question. Do the midgets operate in some kind of hive mind that I control? If so, I would procure a two-person money costume and dance into a bank, at which point they would deliver me to the vault. I would steal as much cash as possible and I would send one of the midgets to the foyer where they would distract everyone with an adorable Russian dance. The other midget would cartwheel away to fame and fortune and they would reunite and clamber back into the trench coat and fuse together to become a Voltron-esque me and I would live like a king.
