FCAM123 line source for compact outdoor 12V application

Hi! I'm thinking of experimenting a bit with line sources for outside use.I read from martinsson that the FCAM123 sounds good outdoors and it looks like a quick build so I already ordered 12 faital Pro 3FE25-16s. Only 12 because my plan is to divide the line array into two smaller, 6-units long arrays that one can attach together to form again the 12 unit array. This way, one can make a mono stack for electronic music (my plan is to use a THAM12 as subwoofer) or have stereo set-up for other applications or locations.

I have been reading about how line arrays behaviour can be improved by means of delays, shading and progressive crossover settings. I'm considering using an NL4 conenctor for each half so I can apply different settings to the lower 4 and the 2 upper faitals with the aid of a minidsp 2x4. This way, when both are attached I'd have 4 zones with 4-2-2-4 speakers each.

Do you have any experiences with such set-ups? Any stuff I should take into consideration?

Thanks!
