switching channels of two amps at the same time

i have a mesa roadster combo and a line 6 Spider Valve MKII 2x12 Combo and im wonder if there is a pedal that would allow me to not only play these amps at the same time but also allow me to switch channels of both amps with one stomp. i want to blend the two sounds of the dirty tone and the clean tones but i dont want to have to step on two pedals to do so. i have a morley aby switcher so maybe im just looking for a pedal that just switches the channels.

You would almost have to go midi.

I would look at the Voodoo Labs control switcher http://www.voodoolab.com/controlswitcher.htm to control the Roadster and a midi floorswitch of your choice. If you want all functions on the roadster your would have to get 2 control switchers. Go directly into the Line 6 midi jack.

Check out RJM too although they are more custom and pricey http://www.rjmmusic.com/ampgizmo.php
