The only advantage of having multiple identical modules is that each module have it's own set of global variable. If this is what you want, then currently you must call Build() for each module, as there is no way to clone a module.

I have been thinking about revising the engine objects slightly. In the new design the asIScriptContext will hold the global variables, and a new asIScriptThread will execute the byte code and use the context when manipulating global variables. In the new design you will be able to do what you want in a much cleaner way, just instantiate an asIScriptContext for each of your in game objects.

I can't say when I will be able to implement this new design though.

I haven't tested that, but I can't imagine that loading precompiled bytecode would be slower than parsing and compiling the script. Especially since you don't have to save to disk.

By all means, give that a try. Let me know if you have any trouble with the save/load feature, I don't know of many projects that actually use it, so I can't really say how stable it is. It ought to work, but there might be some details that I haven't tested yet.
