Why doesn't everyone do ram fill?

I ran dual pumps off a single 1" thru hull on the last boat. both pumps were not starved for water and had good flow. factory pump used 3/4" line, added pump used 1" line to the bags. would do the same setup again only would swap out the 3/4 for 1". The red rule pumps were good for it.

I did a bit of investigating on my 16 mojo and here are some numbers:

3 Pumps @ 11.5 amps, each need 20amps of fuse protection
60 amp breaker feeds the PDM where i assume the timers are?
Each pump is individually wired to the PDM

Would it be possible to upgrade the breaker to 120 amps and splice the wiring to each individual pump to run 2 pumps each for a total of 6 pumps?
Splicing the wire would remove the need for additional timers and timer syncing issues.
Would the PDM be able to handle this extra load?
Not sure what PDM stands for. The part is labeled PDM 12V Skiers Choice. IMG_4394.jpgIMG_4395.jpg
