MAD Bypass Alteration - Risk?

Less is not more in this case.
How the feeds are routed should depend on where the power is going.
Except during start, the power source is the alternator.
Except for when the battery needs recharging, the most direct connection to the items needing power is by feeding the main splice.
(obviously if other electrical equipment has been added or feed routing been modified then this may not be so. so lets look at your case and see how it applies)

I am going to add a fuse block between the alternator and starter relay. Then run a wire from the SR into another fuse block, bypass the bulkhead altogether and feed the accessories .

My thoughts are this would be safer as opposed to running more amps though a bulkhead connector.

Absolutely better to power your new equipment from an auxilery fuse box in the engine compartment.

I don't see any advantage of running two feeds from battery to the new fuse box.
The disadvantage is each additional connection is a potential for resistance.
Also as a practical matter, is it possible to get maxi fuses in the same box as regular fuses?
