Cruise control retrofit

Anybody ever think about trying to retrofit an electric cruise servo?  My vacuum servo works just fine, except it's slow and clumsy due to the lower vacuum available from my current engine setup.  Early electric units use the same steering wheel switch resistance values and VSS sensor, so I was wondering about making a custom cable for one and trying to convert.

Here's what I know:
F8VZ-9C735-BA is the servo for 92 or so Crown Vic
DY588 is the Motorcraft number for the VSS on BOTH CARS
Resistance values are exactly the same for the switches on BOTH CARS
The Crown Vic system uses a pressure deactivation switch (recalled several times) that can be eliminated by running the Key On power to it's pin, probably safer that way, anyhow.
Both cars have a brake pedal feed that works the same way

The big blank is a cable that would work, but it's easy enough to adapt one.

Thoughts?

I like this topic,,

backing up a few steps,,, do you think that the actual solve is to increase the size of the vac reservoir?

I was just wondering, thanks.

I always noticed that when in cruise and going up hill either two things happened,
-the speed dropped but passing gear was achieved or..........
-the speed dropped and then the cruise dropped out as well.
