Hello, this project builds off the the work done here:
https://www.electro-tech-online.com/threads/electronic-firing-system-for-fireworks.21046/
My goal is to use a microcontroller to control the firing of a large number of cues. The exact number isn't important, but at least 64 would be preferred.
I'd like to replace the pushbuttons in the following schematic with mosfets.

The mosfets would be controlled by an led matrix; for example: this or this. The mosfets would replace the leds in the matrix.
Is this feasible? Is there a better way to do it?
Each cue would require 1-2 amps for a few seconds max. Several cues may be fired immediately in succession or there may be a pause of several seconds between firings.
Thank you in advance for all of your help.
