Dulfersitz rappel with backup

Is there an accepted (or acceptable) way of backing up a Dulfersitz (body) rappel, such as adding a prussic extended from the harness or on a chest sling?  Yes, I realize a body rappel not the greatest option, and one can construct an ad hoc rappel device with carabiners the main device is dropped, but I am interested in having a safe (-ish) gear-free rappel option available.

Harness? Chest rig? Prussic? If you are in a situation where you have to use a Dulfersitz to abseil, then you won't have any of those things. You don't choose a Dulferstitz abseil, you only use it because it's your last resort. I know of no way to back it up, it's truly frightening and exhausting. With the Dulfersitz, both hands are working hard, one is holding the taught rope for balance, the other is your brake hand. Both are equally important. Having a prussic to attend to would only cause balance problems. You must keep upright and your feet wide. Make sure your pants are tough because you thigh will absorb a lot of friction. Protect your neck from the side too. No wide neck teeshirts. Tuck in lose clothes. Making all before hand. 

Yeah if you have a harness and a prusik then you must have a carbiner, and at that point a munter or double munter is a much better crappy option.

Haven’t tried this myself (from Andy K’s “Down”).

Guy with flesh isn't doing it right. The rope has to be higher--near the armpits--to reduce the tendency to flip.

Using a Dulfersitz was how I first learned to rappel, and while I agree it takes focus it really isn't all that bad.  The use case is when you've dropped your rappel device and don't have enough carabiners to make a proper biner block (losing your harness, not having any cord for a prussic, and not having a double-length sling for a chest rig is a lot less likely for my use case).  Anyhow, you are probably correct about the challenge of tending a prussic, regardless of how it is rigged. I am just curious if anyone has come up with a good solution to this little challenge.

I imagine a munter rappel would twist the crap out of the rope though?

edit: ok, just learned about the no-twist "hassle-free" munter abseil @ https://vimeo.com/236900693?embedded=true&source=vimeo_logo&owner=38318448
look interesting, will check this out.

That's very interesting.  Does this setup have a name?

(Nevermind, I see it now...the South African rappel)

I've just tried the South African Rappel in my living room and it works, even free hanging. Nice. Less tippy than the Dulfersitz. More forgiving. 

In theory, you could possibly add a carabiner (red) and a friction hitch (blue) to it. Keep the friction hitch shorter than in image. Practice a method of attending to the friction hitch that suits you. The carabiner pulls the rope closer to your body. Maybe it works?

 Still... where there's rope, there's hope. I'd cut the rope and make some sort Swiss Seat, a simple version, then use that one carabiner to rappel down on a munter or monster munter. If you had some cord too, then you could exend the carabiner and back it all up with a friction hitch.
I'd never Dulfersitz. Would maybe South African Rappel. Would happily use a diy rope harness and munter.
