The whole plan is great except for adding LED's. LED's added to a system with a 1000w hps is like using a flashlight in full sunlight. I know you think added spectrum blah blah blah. No, there just simply is not enough lumens coming out of them to do a damn thing. If you want to play the broad spectrum game absolutely do add a metal halide, or better yet pulse start halide.

While the LED's will do nothing in your situation, the money you would have spent on them will buy a 1000w halide a couple bulbs and a couple years of the added electricity.

I guarantee you 2kw on that system with 1 month veg or slightly more will easily net you double what you've quoted so far yield wise, provided you continue to do your homework and care for them properly.

Nice system btw... I'm thinking about trying a very similar hydro system soon.
