...but have had no luck. Fairly wide odd symmetry searches appear to just extend the sloped edge and fail the instant they reach the critical point where they touch the central edge and can postpone no further so I assume this is unsolvable as strict 2c/4 odd symmetry. If solved it would allow for 2c/4 level backs in an obvious way as well so I assume this is covered ground.
I vaguely suspect there is no 2c/4 level back (and thus no convex corner for that 2c/1 sideways slope meeting itself). There are however definitely 4c/8 level backs. The thinnest of those I've found so far:

No luck connecting them to a back corner yet, although I only tried a very little and only for the best looking one. 4c/8 is really quite painful.
I also have some ideas about trying to find a level back with a very thin connection to itself (and thus better hope of connecting to a back corner). Searches in progress, TBD.
I also tried looking for a 4c/8 convex corner for the 2c/1 sloped edge meeting itself. This would provide a level back and be interesting in its own right. No results so far and I'm not sure I can push the searches any further, but the partials are so long this seems very likely to exist. E.g. longest glide-symmetric odd partial:
