So, doesn't this work:

Commercial includes light sport.

Train to proficiency with a CFI-G in a 2-33. Pass a proficiency check with a different CFI-G - this doesn't count as a flight review, but the commercial pilot is now cleared to utilize his/her light sport privileges in a glider as soon as she/he completes a Flight review with any CFI-G.

This probably requires five or six more dual flights than otherwise required to solo, but that's not the worst thing in the world. It's still glider flight training which is eminently more useful in the case I shared than getting power current.

At a place doing a couple weekend add-on, some of this could likely even count as the recommendation flights for the commercial checkride and not really be much of a burden at all.

If the SSA can't work this out with the FAA, will 2-33's suddenly become more valuable?

Break, break.

Did you see the AOPA story about the 16 year old who soloed a single engine airplane a few minutes after midnight the day he turned 16? Later that day he soloed a twin engined airplane and a glider. All with just a student pilot certificate. However, a lapsed pilot can't solo a glider in an add-on program.
