Going big for the right reasons is very good. It is possible to waste space if not thoughtful.

The speakers can be as big as you want so long as you don't want to move them often.
Also you might want to remove them from the room if you move house so the door sizes vs speaker sizes will be important.

Tell your friends you got the MWM speaker stack when you set up for the Grateful Dead.

Sound Quality vs. Sound Quantity

The K402 over Jubilee gets very good reviews for natural sound quality. Invest in a few room improvements, along with measurement+equalize equipment.
======

You could purchase a second set of plastic K402 horns and build/experiment a 200Hz Synergy horn which promises better sound quality, plus a good path to room-equalized deep bass. Plans for a wood K402 are on the net.

Agreed, my post wasn't about space savings/efficiency, just I found I preferred the more 'open' sound of a large horn size flat baffle loading the drivers in a corner horn configuration over the corner loaded compression horns.

If I could afford to build a whole new system it would have [8] HE 15"/channel to get efficiency up 'close enough' to the HF horns.

Yep, typical big systems discussed/built on most forums are all about efficiency/SQ in a HIFI app, not how loud they play per se. To go 'live' OTOH takes a bit more: 20,000 Watt Home Hi-Fi System

Don't much like the multicell crammed into the mid horn, though depends on the XO as to whether it messes with the critical mids that these big horns do so life-like, but otherwise like it.

Looks like early 15" Lansing/Altec 515? assuming the mid horns are WE 15, though baffle depth appears to be too shallow for a reflex. Makes me wonder if it's some kind of weird hybrid OB.

My Altec 515Bs have a ~97 dB/m mid band efficiency, so [8] would be ~106 dB/m down low where there's good coupling efficiency.

From the shallow depth it looks like OB IMO. The hole that looks like BR might come from some experiments or parts recycling.

Ive had Jub clones... Amazing. Id sugest not doing the MWM, The Jubs are vastly more interesting and an easier package to live with. Ultimately I sold my Jubs as they were too big for me let along my wife. If you go down the Job route, PM me. We developed a 2nd order crossover... All passive crossover... A SET 45 amp will make them sing.
