1202 Transponder Squawk Code - In a Tow Plane?

Just wondering about something.

Those of us with transponders in our gliders squawk 1202. Hurrah for our unique code. As I understand it other VFR aircraft with transponders typically squawk 1200.

I would assume that at many gliderports few of the gliders have a transponder due to the cost and them not being required (but the trend is towards getting them). On the other hand tow planes would be more likely to have a transponder.

I suppose that the answer will be "no" but I thought it might be interesting to ask the question Is it legal for the tow plane to squawk 1202 instead of 1200? This could let the controllers know GLIDERS are in the area and might "scare away" the heavy traffic. Plus the non-circling tow plane would be less likely to be confused for a flock of circling birds!

I anticipate that someone will mention that their operation always calls the FAA before each day's operation to alert them. Good idea! But having actual "glider" traffic being seen on radar might be even better.
