ePMP3000 - RF Elements Horn - splitting sector from 60 degree to two 30 degree sectors

We’ve been using the ePMP3000 (not the 3000L) plus the 60 degree Dual Horn. We’re hitting a capacity limit at a specific site and would like to split this sector into two 30 degree horns.

Obviously, we’ll lose the Mu-Mimo but at 30 degrees, we would lose it regardless and we primarily need the bandwidth capacity.

Can this work? I see there’s 4 SMA cables for each chain. Is it possible to use an RF Elements horn with the regular ePMP3000?

Or would I have to go down to something like the 3000L? And if so, would I still be able to achieve the same bandwidth per SM (~120Mbps on 20 Mhz carrier?)
