Diagonal on Multiple DIY Packs

[Skinny76]

I currently have 5x280ah 48 volt Eve cell packs that are each wired into a bus bar and each has their own 150 amp bms. I was wondering about putting them into a diagonal configuration, but wasn't sure if it makes sense to do so. I will max out at 250 amps charging and discharging. I have one 2/0 guage to my busbar from the inverters and 2 guage from there to each positive terminal and two 6 guage to each c- of the bms, then two 6 guage to the negative terminal from the bms b-. My questions are:

1) Will each wire between positive posts need to be 2/0 guage also in a diagonal configuration?

2) Will I connect a bms as I normally would to the negative terminal, then connect the c- to the c- of the next bms that is connected to the next battery and so forth and then the last bms is connected to the busbar via two 6 guage wires?

3) Do I need all the wires to the bms's to be able to handle at least what the 2/0 guage is rated for?

It just looks sloppy now and I was hoping to get rid of all these long runs of wire.

Thanks in advance and let me know if I'm not giving enough information for a good recommendation.

I looked this over again and I will need at least 2x4awg from the busbar to the first bms. I'm not sure I need 2/0 awg to all the positive terminals, just the first from the busbar maybe?
