You have a lot of parts. I'm not sure how they will all fit together.When I built my system I studied lots of stuff for almost 18 months. I went over Griffin's paper until I knew it like the back of my hand. I carefully matched all the parts together so that the electronic crossovers would work and then I adjusted the crossovers. What you have maybe might work, but you can't use an off the shelf passive crossover.
Making line arrays is HARD, everything has fit together just right.
I don't think you have enough stuff, but without all the spec's for everything, we can't really help.
I had specifications for every possible thing. Without that, my opinion is that you would do better with one of the plans that other people have made. Maybe someone else has a simple solution for you.
