Can I use 2SK1058/2SJ162 lateral mosfets for this project and if so what would be the max operating voltage and bias I can use?
second, if I use your set up (Toshiba 2SA1943 and 2SC5200) can I drive it with a +/-40VDC operating voltage?

Increacing the voltage but keeping idle current same will not increace the class a power output.
Power output to your speakers can be calculated as (transistor idle current x2)^2 times speaker resistance (Power=I^2R).
Therese not much point in increacing voltage, as things are already very hot. 1.5amps times 24v times 2 that is 72watts of heat.
