To fit a turbo boxer 6 cylinders in a lmp designed tub is basically impossible, the most rumored options are the cayenne derivated V8 or an updated version of the 918 V8 (that basically is an updated and enlarged version of the rs spyder engine).
Since audi and porsche will have a customers program too, likely engine will be as simple as possible to keep engine managment/rebuilding prices reasonable also for private teams.
I don't expect stuff like heavy reworked or semi-bespoke high efficient turbo V6, lmdh simply doesn't need that being a bop class. Look at acura dpi, its engine is pretty good and powerful despite being an enlarged racing tuned honda accord V6 of about 20 years ago...
