Multi-band WSPRing?

Now I have my fully stand-alone 10m WSPR-AXE unit, I should be able to WSPR on MF (with the earth-electrode antenna) or on 6m at the same time. I have yet to try this out but this means I can WSPR on 2 bands at once should I want. 6m might be fun although I've had no success to date lately on 6m.
