I think you will hit many other issues if you try to run two instances
of QEMU within a single process.  There have been several efforts to
simulate heterogenous systems (e.g. different CPUs as part of one
computer).  Some of them run multiple QEMU instances and communicate
between the processes.

Before going further, have you looked into existing work on emulating
heterogenous systems under QEMU?
