You have the sources so anything is possible.

To send different packets to different stacks you will need to modify
packages/io/eth/current/src/net/eth_drv.c. In eth_drv_init it calls
if_attach() and ether_ifattach(). You will want to modify this so that
it attached different drivers to different stacks.
