I want a ccs variable from 1.6 to 1.8A, a little more than a single LM317 can supply. The circuit should be simple and cheap. So I came up with the design shown. I know there are higher current regulators, but they have more disadvantages.
Is it alright or am i missing something?
Nothing to do with audio.

Should work OK. The nice thing with current sources is that you can just connect them in parallel. The Zout of each prevents the other to supply current into the other source. I think your circuit will work as required.
I actually think you don't need the OR-ing diodes.

National recommends 0.2 ohms at the output when paralleling the two 317s and mine are over 1.3 ohms. I will try without the OR-ing diodes.
In the final circuit, I will keep the diodes, in any case, for preventing catastrophic results in case one 317 fails.
