I must admit this is the most elegant solution. However I finally realized the problem with my solution as well as yours here! How would we get away with that money? So once faced with this dilemma I realized I had to plan this entire mission better.
So here is my revised plan. Fly in with C5, land on street. Kneel the C5 and drive out in your Abrams.

Roll deftly over container, pop hatch on bottom, pull container/money in, draw troll face on concrete with sharpie, button up bottom hatch, turn turret and drive back into FRED. Unkneel the bitch and take off. EASY PEASY
Unfortunately this plan would probably cost all the 3 mill and then some LOL. But I bet it would work.
