I don't really think you'll have an issue. Heck, if you really want to run the clean stuff, run JP4 through the system! All a jet engine is is a fancy diesel motor. The original diesel motor was designed to run on peanut oil! I'm sure any oil based low volatility product would "fire" just fine in the motor. All you need is a fuel that will fire upon compression. That is why you can dump veggie oil into the system without any type of distilling and your motor will run just fine. Now you might ruin some seals in the fuel system with the alternative fuels, but the motor will run. Some fuels have more cetane value than others, so there will be a power difference, but it should run just fine. I'm curious to hear about your results.
