No, you can never "just bump the fuse" to increase capacity without doing a proper analysis. Also, do you see on that fuse housing "42 Volts DC max"? This is safety margin and also allows for inrush currents (same as the pumps 20V vs. 11.5V). The Carling rocker switches are rated to 20A so definitely no option to run 2 pumps in parallel.

6 pumps is doable but it ain't gonna be cheap. Cost vs. benefit starts to fall apart real quick.
