I strongly suspect that the answer is no, for the following three reasons:
1. Time- Each switchover requires uninstalling and then reinstalling 30 screws.
2. Screw failure - With 30 screw uninstallations and reinstallations for each switchover, eventually an adaptor plate screw is going to get cross-threaded in the ski inserts (if using a ski w/ insert), an adapator plate screw thread is going to strip in the ski (if using a regular ski), and/or a Dynafit binding screw thread is going to strip in the plastic plate.
3. Extra weight.
Drawbacks #1 & 2 could be lessened somewhat by having two adaptor plates, but then the cost for two adaptor plates is starting to approach a second pair of Comfort bindings.
