kelsey hayes vs f/m/j swap

I have a couple of questions that i hope someone might have some answers to.

First off, on my demon i have what i believe to be the kelsey hayes disk brakes on the front, and stock drums on the rear. Are this brakes adequate enough to stop this car? My uncle always complained how they were not up to par with his standards

Can i get more braking power out of the f/m/j swap, or is the kelsey hayes about as good as i can get?

I dont really want to look at the expensive conversion kits for the drum spindles because i plan on eventually getting the alterkation k member, so cost efficiency is definitely a factor.
So in short, should i just rebuild the kelsey hayes system or go the the f/m/j spindles and calipers
