3-in-1 Exo Force Combiner!

One of the key features of Lego is its ability to be rebuilt into new creations, and I think that one theme that did this particularly well was Exo Force. Many of the sets had alternate builds, making mechs into all sorts of other vehicles. The two sets I've taken inspiration from here, Stealth Hunter and Grand Titan, actually had a third option for rebuilding: a combiner mech! I think this would be a great GWP since if offers 3 different options for people to build, while also being faithful to the original sets they are based on!
Note: the alternate builds for the single mechs use only pieces from their respective mechs, so you can mix and match having one mech and one alternate build!
