Yep, something like that, maybe a little bit more elegant
. Since (I believe) there's still some room for improvements, let me share my experience with the issue. Of course your device does what it was designed for, allowing for take off and landing on relatively calm water surface at the obvious expense of somehow handicapped aircraft. The range and agility must be taxed significantly: I assume 7-10 minutes less of average flying time on fully charged battery. Nobody sane enough expects anything better than that. If your floats withstand somehow rough emergency landing in case of power shortage, than the goal is achieved.
I went a bit further with the concept, building wider and sturdier structure to provide stable floating on rough waters, create better clearance for the camera and minimize the negative force of downward thrusting props. Floats are secured to a frame with steel linkage, providing sure buoyancy in case of catastrophic malfunction and crash landing.

Here's the Matrice 100 with floating attachment. The concept was employed successfully for Phantom and Inspire drones as well, although the complexity of design renders no commercial value whatsoever. It's strictly a hobby project, that's all. The device was developed for one and only reason: to control UAV's from the boat full time, 24/7, during long summer expeditions. Take off and landing on the boat deck is risky and difficult, hand catching equally challenging due to somehow limited ability of myself ... If not these factors, I'll never consider such modifications to be all the efforts worthy. Works for me charmingly ...
