You can also add lime to the mix. I'd stay away from adding to many colors. Once you factor in cost and time, it's usually cheaper to buy a cheaper Chinese fixture. Like the ocean revive slim fixtures. Pretty good and really similar to what you're already building. I personally stopped building fixtures with lots of single chips. You could easily run some high powered LED chips and shave the size and work down. I like using bridglux vero 10 and philips luxeon K multi chips.
