Imagine this...

Use the extremes of your imagination and picture the following:
Take the Deluxe Transformers: Prime Soundwave figure and repaint it primarily Blue with yellow and red details details. Fold the legs together as if transforming him to vehicle mode, then spin them around 180 degrees, so the "cockpit" of the predator drone is facing forward. Give him a Beast Machines Jetstorm head.
Take the Deluxe Transformers: Prime Arcee figure and repaint it purple with yellow and grey details. Unfold the wheel halves in each leg, and combine them together, but don't fold the legs like you would to transform. Have the figure "stand" on the wheel and give it a Beast Machines Thrust head. And maybe an altered chest. If you're bothered by that.
Take the Deluxe Generations Warpath figure and repaint it Navy and Silver, with Red details. Give him a Beast Machines Tankor head.
Three easy, good looking, deluxe Beast Machines figures with very simple modifications.
