Keg still with keg thumper and steam injection

[seabass]

I'm rebuilding my still to accommodate a thumper . It's going to be a half barrel keg with a 5500w element driving a 1\6th barrel keg thumper. It will be very similar to Yummy's design except there will be a lot more triclamp pieces so I can set it up for stripping runs and other things. I can also use a half barrel thumper keg.

My main question is whether it is reasonable or wise to also use this setup for steam injection. Is it possible to use this same thumper setup with the boiler filled with water and a half barrel keg as the "thumper" filled with bourbon wash? I would only consider this for distilling on the grain, but I want to make sure that I'm not missing a major danger or being a dumbass.

Since I don't want a PRV when using this as a typical thumper and potentially venting alcohol vapor, I'd have a triclamped tee with a PRV on it to put inline for using steam. I'll make sure it's directed in a safe direction. Am I missing anything?
