I'm curious if any of you guys have ever tried to self launch with no
wing man on a cg hook only glider.

I do it regularly. No problem, neither winch nor aerotow, neither paved
nor grass runway, if the grass is not too long.

Start with aileron and rudder fully deflected, hold them fully deflected
until the wing rises and then correct as needed. Be prepared to release
immediately if something goes wrong.
