fabricate combat uses

If you use a feature such as Arcane Abeyance or similar to avoid the casting time on the spell fabricate, could you use it in combat, for example, turning an enemy in plate armor’s armor into an iron maiden on them or a rouges leather armor into a gag and restraints? even if you cannot build it on another creature, removing a tree from under an enemy scout. it specifies "raw materials" however that is not defined, nor is the required area for the item to be created, only for the raw materials so could you turn a bunch of wood within 120ft into a block of wood 100 miles in the air? it also doesn’t specify how the raw materials move, if an enemy is between a tree and where I place my block of wood, does the tree move around them to avoid harm or would it go through them? it also does not specifies how many resources are needed nor whathappens to extra resources, if you cast the spell targeting the 120ft cube of the ground in front of you and want to turn it into something "large" would it all be compressed, some of it left where it was, or just vanish?
