I recently ordered AM Leo Prime with a few extra add-on parts:
2x AM Leo Prime- I ordered 2 to do the left leg swap and fix the ridiculous stump they gave him.
1x Scout Class Sunspot- I'll attach him to Leo Prime as a flight pack- which, if my plan works the way I hope, he should be able to transform with him attached- no removal needed. I'll be using his thigh armor holes as connection ports for the pegs in Sunspot's feet. That is, if they fit....we'll see.
1x TF Prime Sergeant Kup- I'll attach his cannons to Sunspot's arms as back boosters.
1x Bot Shots Optimus Prime- For his new head.
I also ordered Sunspot to add more yellow to Leo Prime's overall color set. What I believe drew most fans to the original Lio Convoy was his unique amount of gold, specifically in his mane- and seeing as how the new figure doesn't really have that, I'm adding Sunspot to increase his brighter colors.
If this works, I plan to order 2 Black Leo Primes, a Bot Shots Nemesis Prime head, another TF Prime Sergeant Kup, ROTF Scout Class Skystalker, and do the same thing. I'll post an update soon. ^_^
