use keystone on sub-mix - then all perspectives and scales on layers stay aligned - and you can playback multiple layers on the same object - keeping everything aligned - just by routing a layer to an output mix - its much much easier.

use one sub-mix for each object on stage-

you will need an alignment image which allows for easy adjustment for every object on stage - probably matching the aspect ratio of the objects on stage.
Of course using Mixes is the ideal way to go....as long as you have a full PRO version server this should work well....otherwise you will run out of available Mixes fast.

So in this case, set up 6 Mixes, 2 per "output" of the Triple head that cover the entire raster of their respective "output", and then you can use the Mix Shape Control to adjust them to fit the set pieces.

If, for some reason, you need more than 8 Mixes at once to do this, you will get in to trouble, and have to use some of the steps I listed initially.
