As Dave said, and I said before, experiment. It is the only way to originality. The only reason certain orchestration techniques work is because people do them. So do yours, and maybe we'll follow. Start there. See if you have something magical that can break some new ground, before turning into a slut. That probably sounds rude, but I am just being frank (not calling YOU a slut at all).
Orchestrational technique is a set of preexisting notions. If you experiment, you will cut through the icing on the technique cake, and reach the ultimate goal of fundamental understanding. From there you will have MORE power than an orchestrator in your hands.
If you ever want lessons on how to achieve that, which is what I teach (self realization technique), I can help from a place of someone who understands all the variables. You can PM me if that's something you are interested in. Otherwise, I'd be glad, as would other forum members, to hear what you come up with, and lend some comments to see if we can take it to the next level of understanding.
TIPS:
Layer in parallel for toning. Create atmosphere by way of filling in between the notes (fundamental Ravel method).
Ravel specifically said when asked the difference between arranging and orchestrating:
"Arranging is the assignment of compositional notes to instruments ... orchestration is the atmosphere that is added around those notes."
Yes, it's a little obscure, but it has a fair amount of truth to it. And hopefully it will spark some direction into your "dig".
