Yes you can do this.  I did this to try to debug some things in messages
when I didn't have access to a debugger that could handle dynamically
loaded objects.  The only thing is the assembly code that triggers the
dynamic loading must still be there.

Yes you can intermix them.   The major stumbling block is that ATK
believes it is control of the event loop.  Your code must be written
using an event driven model.
