Can an iRig Mic HD 2 and iRig Pro Duo I/O work together?

[grass]

Is there any way to feed the output of an iRig Mic HD 2 to the iRig Pro Duo I/O? I want to use one input line of the iRig Pro as input from the Line Out of my guitar amp. I need a voice channel too. Do I need yet another standard mic for input to the second channel, or is there a way to use the iRig Mic?

Both devices won't work together on a single iOS or Android device. You may have better luck on Mac using aggregate devices and possibly on Windows with third party software but it would take some doing even there.
