Mixing types isn't supported - you can't create "new" classes of objects for halo. Destructable scenery doesn't always sync and ai certainly do not so what ever could be made by mixing them wouldn't be worth it for multiplayer anyway.

List of thing that do not sync to my knowledge without intense scripting or not at all
-AI
-Regional Damage
-Biped damage
-Animated scenery (Sorry to burst your bubble.... Again....)
-Vehicle destruction is a maybe... I'm not entirely sure on the matter...
-Destructable Scenery-depends on scale....
There may be more things that I'm not thinking of at the moment....
