It might work to live in, depending on the siting and site prep.
I don't know if it would be advisable to put in a solar tube, as it would penetrate the water barrier, but it could be doable with proper sealing. It would certainly light the place up. If the house was on a flat or a low slope and the mound was the high point, then a solar tube would be more appropriate. You could also put in a courtyard or light well on the uphill side, like an Oehler home. You could also run the solar tube from the front wall, like a chimney pipe. I have a 12' vertical run with a 21" tube and it brings in plenty of light. 14" or bigger in a solid tube could probably run up to 20', with a couple of angles. without losing too much light. You could also experiment with water-filled tubes.
I might be inclined to bolt or spike the logs together, just to be on the safe side.
Pretty much any traditional dugout/pit house/earth lodge design could benefit from good site selection and prep, a water barrier, proper drainage and insulation.
P.S. For future reference, " = inches, ' = feet, not that I was confused.
