Having ground looped once on a winch launch (inexperienced wing runner and
tall grass) I doubt I would ever consider this on grass or dirt. A paved
surface might be okay with a very experienced pilot. A wings level assist
would be good, but might be moot if the up slack just pulled the glider off
the leveler. Holding a glider with airbrake/wheelbrake combo level doesn't
seem prudent. The more bothersome aspect is the lack of another set of eyes
to visually check the launch zone for encroachment.

Think I'd prefer to file this in my never do list (from a winch driver
perspective).
'Never winch launch unassisted'
'Never winch launch downwind'

The point is this "cartwheel scenario" has happened before.
I believe there was a case in Europe not that long ago.

You need to be "very very" quick on release if the down wing

You don't start with a "down wing". You prop the wings so
they're level.
