OB with multiple 3 inch FR drivers

Hi,

I am planning to make my first OB speakers for which I will be using eminence alpha 15a two nos per side (top and bottom) and for the mid section I am planning to implement 8 nos per side of FR Tymphany TC8FD05-04 3. Aim is to look like a tekton

My question to all experts here is, is this a doable thing? what are the pointers I should be looking for

for crossover I am going to use a dbx234x but I understand that I need to split further at FR region.
 
that fullrange is given for 20W 20Hz ~ 10kHz so I guess you would insert a tweeter for the upper octaves.
A la tekton it means that those FRs are in some sort of circular(square) array, right?
There are some threads here at DIY talkin' about it.
Some others are about linear arrays, where "beam steering" is probably the thing you mention when saying "do more X-over work for the FRs"

A la tekton it means that those FRs are in some sort of circular(square) array, right? Circular array of combination for series and parallel to for final impedance of 8 ohms

Implement it in a similar way. Basically, the cluster of drivers are split into three groups each at different frequency ranges.Only one (the center) is the tweeter, one group is a high-mid and one is a mid-mid setup. I'd copy it.
