With a little electronics to achieve regulation, and current limiting, it should be fine then? My assumption is that the circuitry inside a modern LED light will be controlling current anyway.

I was under the impression that the dyno works like a permanent magnet AC machine (voltage determined by the speed of revolution), and current determined by the external circuit and winding resistance, i.e. as a voltage source.
The other point was whether these lights have a DC blocking cap on the input side. To me that seems highly unlikely, since it would have to be an AC cap rated for full current.
