These "oddball" configurations are a mainstay of future projects work, and entirely conventional in that regard. They invariably however manage to miss a few big issues such a handling qualities (TURIN's deep stall), evacuation criteria, or simply the ability to park at a normal airport. Which doesn't mean there isn't value in looking at these things - just you need to be very careful to spot what's missing in any given feasibility study.
