I have always wondered if using a aftermarket electronic servo controlled cruise control tied to the foot pedal and using a single resister to determine the speed setting would be a viable alternative for us guys with GAS engines.
something like this:
Audiovox 250-1316 Ultracruise II Universal Electronic Cruise/Speed Control This Cruise Control system by Audiovox is the more reliable and easier to install than vacuum operated units. It makes a great addition or replacement for an existing unit tha

Apparently is is Made by Rostra Precision Controls and I guess Audiovox rebranded some and sold under their name.
Anyway, here is the correct manufacturers page for the control.

Hahahah I get it now.
Aside from the nightmare of the installation. You would need a Timed signal source to go to the VSS (vehicle speed signal) input wire to "fool" it into thinking the vehicle is running (wheels turning) The frequency of that signal would determine the engine speed.
Since it says it takes a sine or square wave input, a simple circuit to produce the appropriate signal can be made easily. That circuit could have a potentiometer on the dash it to vary the frequency and then be able to have variable high idle RPM
Since it uses a tachometer signal to shut off the unit if the transmission is accidentally knocked into netral, you would leave that wire disconnected.
(never did like installing them due to the mechanicals. Just my weirdness, I guess.. I put one on my Motorcycle and it works good.)

Here are some examples of the kind of circuit:
RMCybernetics - DIY Homemade Signal Generator with Pulse Width Modulation
Here is a electronic function generator kit that would do the job for 6 bucks and a few minutes of assembly:
Signal Generator Electronic Kit MK105
Just some ideas to start with....

Shoot. I almost forgot.
This is the installation/owners manual for that cruise control

Don't worry. there are still problems. The idle running away in to high rpm's without having a load on the engine is one of them. The vehicle going down the road is a load that causes a limit.

Here is a simpler and cheaper version. 
Get a electric door lock actuator or rear hatch actuator and mount it to the fenderwell, it needs alt least 3/4 to 1 inch movement. after all, we are really only looking to go to 1200 rpm or so.
Make up a cable bracket like the cruise control.
find a motorcycle cable to operate between the door lock actuator and the throttle cable end with a adjustment screw that is already on the motorcycle cables
Hook up the cable at the throttle end exactly like shown in the Magnavox instuctions The cable has to have enough free are (no sheeth) and slack to ensure no interference with normal throttle.
Use a dash switch to activate/deactivate a latching RELAY. wire up another relay to the Brake wire to disconnect the latching relay power if the brakes are depressed. (brake wire availabe at the connecter and harness for trailer controls)
Add another relay to disconnect power if the trans is anywhere but in park.
