My thinking is I want to make less hp and use less gas, the two are related.

As you mentioned, this works for
gas, not diesel.
But there are whole threads on this, and we don't want to go OT, do we?
Do you like your Diesel warm or cold ?
Now, back to warming diesel fuel...

I was thinking more along the lines of increasing temperature and pressure making use of diesel's explosive properties, but maybe there would have to be air in the mixture for that to happen?
I think you are right.
HDi commonrail TDs have 3-cylinder high pressure pumps which can deactivate one cylinder, for example at low loads. I might have something mixed up, but the cylinder may also be deactivated when the incoming fuel's temperature is too high.
BTW, does heating diesel fuel excessively lead to a degradation of its quality?
