Call me obsolete, but I don't believe in fixing what isn't broke, so other than Be [and even then JMMLC told me he could only just barely tell the difference between it and alum], I'm leaving well enough alone. As for Ti, I've only auditioned a few versions and all sounded like a metal shop brake shearing sheet tin.
Makes my teeth hurt, but then a lot of folks like sibilance to the point of boosting it as much as 6 dB, so can understand why many folks prefer Ti or similar.

It looks like stamped 1050A part, the lamination creeks looks very deep, this finish is often used for alimentary parts like dining plates.

Celestion Axi2050 AxiPerodic 2" Wide Bandwidth Compression Driver 4-Bolt
Finally made it to America
Pair of used Axis for 1000
Celestion Axi2050 | Full-Range | Coal Valley, Illinois 61240 | Audiogon
Can I really add another pair of drivers to a horn? No complications?

The Radian diaphragms seems to be made of 7075 with a post forming heat treatement for stabilisation and hardness but i don't know anything more about the process. It is the only way to build a durable and stable dome made alumnium submitted to a gigacyle stress.
Multiple drivers can really be added to a single horn, but getting good results is not uncomplicated.
Dimentionnal sprecifications tolerances can change the cost to X1000
Geometrical sprecifications tolerances can change the cost to X1000
An alloy specifically developped for an application change the cost to X1000
The assembling process performed by trained experts change the cost to X1000

Don't know unless the [various] JBL systems used in the local Regal Hollywood Stadium Cinema 24 multiplex use them in which all the ones I've visited are so broadband 'bright'/unpleasant to the point of having to sometimes stuff my ears with cotton, and my hearing 'drops like a stone' above ~12 kHz, so quit going.
The 'Private Ryan' movie had me and some other older seniors walking out for a refund.
That said, I've since come to the conclusion that it must be Tinnitus related, so YMMV.Regardless, should work fine if the driver is designed for it based on my airbrush misting/coating Ti, [Altec] Symbiotik, piezo with Dammar for HIFI/HT apps.

How about a line-array?
9 compression drivers in each cluster (element) X 16 for the full (supercluster) array = 144 drivers.

Seems like a good opportunity to revise this concept:
An externally hosted image should be here but it was not working when we last tested it.
Here's an article about dual versus a single driver attached to one horn. It doesn't seem worthwile, but the manifold (adapter) looks like a huge bottleneck with its sharp angles and pinched throats.
For dual-Axi2050 duties, a traditional WE/Altec type short exponential manifold might work better, perhaps with vanes near the exit. The manifold could be attached to a properly sized (conical) mouth section, think: Klipsch K402. This way you'll end up with good loading as well as decent directivity.
Or just clone an 18-cell WE/Vitavox/Altec horn
