Travis, there’s nothing like a bit of ‘documented craziness’. You’ll be fine and you’ll have great company along the way. The long lead line on the Group means you’ll have plenty of time and space to plan and experiment. At that scale my advice would be to keep the dio to a stand - the Preditor has to be the singular focus and going over-elaborate may take away from the work.
Foe example. If you look at the model below...
And compare it to this model...
Model 2 is simpler, less busy, and much more powerful for my money. Thinking about this in respect to your ‘Yoda’ Build, Yoda’s setting was important, integral to the build and narrative whereas with a predator you expect him to blend in, to be part of the terrain, so the focus on the subject becomes more important.
My 2 cents worth.
