Prusa Quad - 4x size print bed ideas?

I currently own 3 Mk3s along with my orig Prusa mk2.5s. My company is growing and need more parts faster. Running Volcanos with 1 mm nozzles on two Prusas to make the same parts over and over where appearance doesn’t matter(inside a machine). Due to 250x210 print bed size, it requires me print 13 separate pieces and glue together. Does anyone have knowledge or interested in working together at building a 4x larger x-y  frame and using sacrificed parts (Einy, motors, sensors etc) of a mk3. Aluminum extrusion frame, keep z at 210mm and mount 4 mk52 print beds side by side to make 500mm x 400mm over mounted on an aluminum 4x y-slide frame to hold these aligned to create one continuous print surface. X-slide is lengthened as well. Alternately, if there is another large print bed available.  After the firmware mods to accommodate the Volcano, I feel the firmware can be rewritten to increased x-y and to locate Pinda Sensors on new 4x bed. Any thoughts?
