For temp control your going to have to lie to your printer and set it up as a second hotend.. no support for second heated bed in any firmware that im aware of.

I would probably just get a arduino and plug that into the Sevenswitch, set that up as a independent system

You'd have to use the Fan output as second extruder heater ( D9 ).
Also #define MOTHERBOARD BOARD_RAMPS_EEB ( #34 ) instead of RAMPS_EFB in Marlins configuration.h.
Then change thermistor definition for T1 to match the new thermistor.

A little more information about what you're trying to achieve would be helpful.
It sounds like you want to have two heaters and two thermistors in a single hot-end? What do you want to measure with the second thermistor? How will that differ from the first thermistor? If it's not significantly different, then just use one thermistor to control both heater circuits. But then, why not a single more powerful heater?
Or do you want to have *two* hot-ends each with a heater and thermistor? And presumably two extruders.
