I'm beginning to see a way to do this... looking over the ground plans, most scenes are right on with the projector, there are only two spots where it is important to keystone.

If I'm understanding correctly, I need to adjust the scale and aspect ratio of one mix to hit all the boxes in the view of the projector, then keystone to lay flat on them (lucky for me, they are all at the same angle on stage) Then, I can scale my layers as normal to fix the boxes.

It would be nice if I could adjust the other parameters of my shape via DMX... the options are there, but I can only set them via the GUI. But, it looks like what I need right now is possible.

Thanks!
