An Electrical 'distribution block' for extra Switched items ? Options

[Literati914]

I'm adding several aux items to the electrical system of my '72.. most of which will be powered thru relays (constant + and switched power). The constant power will be via an extra fuse block that I'm adding over towards the right hand side of the steering column w/ a red power wire directly from the battery.

My question is - can I simply add a single wire from a switched location on the OE fuse block (#9) and run it over to an aftermarket 'distribution block' at the right of the column?

This way I could potentially add several 'switched' relays off of it, as well as just switched/non-relay items.. while not cramming so many extra wires into the stock fuse box. This seems preferable but I can not find an instances of anyone going this route. So in theory it seems logical to me - will this not work ?

Most relays fire with less than 1/10 of an amp.
You can trip a shitload of them on a 10-amp circuit.

Adding anything with either a motor or an incandescent light increases the load on a circuit.

I wouldn't want all of my relays firing at the same time an electric motor is running.
Sometimes you need to add a diode to electric motors because they can become "generators" for a short period of time after the circuit is turned off and the motor is slowing down.

Fiat Spiders are known to have the radiator coolant fan do this shit.
You turn the entire car off with the ignition switch and the critter runs an extra 3-5 seconds and the coolant fan spools down.

I try to keep shit like that out of my trigger feeds for my relays.
