I have doubles in 8kg increments (24's; 32's; 40's; 48's). What worked for me was working with a single bell for a while, in my case I did mostly ROP-cycles, which got me eventually strong enough to start with the pair of those bells. With the double bells I'd also do ROP ladders or run some S&T/Strong/Giant cycles.From my experience I will say that humping from 2X24kg to 2X32kg would be rough. That might be the only flaw in your plan. I had the 8kg jumps for single Kb work for a long time, but as soon as I mixed in doubles, I invested in doubles at all of the 4kg increments as I go up. It’s a slippery slope, no matter which way you go.
I do have a barbell, which is for me still the best squatting option. I've tried the double kb front squats, but I do find them more challenging to the core and back/shoulders than they are working the legs. Squatting 100kg with a barbell is pretty easy for me while squatting double 48's is hell.
