I don't know what your load is so If the choke presents a greater impedance at lower DC currents will it cause a problem? Could it resonate with the load's capacitance? It's generally not a good idea for a power source to have an output impedance with a significant inductive component. It's a variable that I'd prefer to not have to deal with.

However, when you get this thing together, observe the voltages after the choke under varying combinations of frequency and current to see what's there. If you find some sort of instability, you might be able to modify the choke by reducing the number of turns. The inductance at full load current won't change much, but it'll reduce the inductance at low current considerably as inductance is a function of the square of the number of turns.

Let us know how it goes.
