Wayne,
I also would be interested in such a endeavor. I have eight (8) 2226J's in my collection and would be interested in using pair of 2226J's with my Altec 288C driver on 311-60 horn with 600 hz pi x-over in the M-T=M configuration. Just think about it, JBL bottom end w/100 db and Altec horn/driver combo @ 115 db for 15 db attenuation/compensation would be killer. The JBL 4648 cabinets (I have 4 decent and 1 cracked cabinet) doesn't leave any room for the horn between the two 15" drivers. (BUMMER!). I know from Sam on this forum that @817 hz there is cancellation between the two 2226's, but a system such as this would best be with 1.4" or 2" throat drivers for high end, so 500hz/600hz or 800 hz would be good x-over prospects.
I think for anyone going this route, 1" drivers would be a problem since the crossover should be crossed over lower than 1.6 khz.
Regards, Ron
