You'd have to scale things a bit, but they could be useful.
And I found this much older design that has some similar design characteristics.

A scale modern glider at a 1m span is going to have a pretty small fuselage for electronics. You may end up wanting to go with an older, low aspect ratio glider, or a larger wingspan.
