A bit late to the party here, but I have plenty experience of experimenting with this sort of stuff on planes/wings.
Generally you can get a rough idea of thrust by looking at how much air they shift. 4 inch X 3 inch pitch x 2 blades = 4x3x2 = 24. 3 inch x 3inch pitch x 3 blades = 3x3x3 = 27. So theoretically a 3 blade 3" prop could be giving more thrust than a 2 blade 4". There’s drag and other factor to consider, but…

I have a premium sub, but the free version is good enough. Just pick a random motor that looks roughly in the right ballpark, a battery size and a generic 30A ESC or similar, then start tweaking the prop dimensions to see what effect it has on thrust and power/amp draw. It’s designed for wings, but you’ll soon start to get an idea of what sort of props might be feasible.
