The only thing stopping most of them is a too-high Vne. There are a
number of older two seat gliders with Vne until 120 knots:

Ka7: 92
ASK13: 108
Janus: 119

It's easy, and I suspect even legal, to simply make up a plate with a
lower Vne than the manufacturer originally specified. There are many
cases where a glider model's Vne has been reduced due to problems
discovered later such as flutter. Can you (or your engineer) reduce a
single glider's placarded Vne because of repairs, or simply because
you feel that it is "old"? It's no great hardship in most glider
flying to lose a few knots off the top speed.

I've definitely seen a powered aircraft operated as a LSA by replacing
the placard with one specifying a lower MTOW (which was then
ignored...).

You may have seen a powered aircraft operated as you describe, but not
legally if type certificated. Limits for determination
of LSA eligibility are as originally certified.
