There is a StartCombat function that triggers a function at the end of the battle. This function passes the hero and the result of the battle for that hero. How can I add more values to the parameters being passed?

You can redefine the function itself so that it returns the result of the battle:

local wrapStartCombat = StartCombat
function StartCombat(hero, enemy, stacks, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18)
	%wrapStartCombat(hero, enemy, stacks, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18)
	local combat_index = GetLastSavedCombatIndex()
	while GetLastSavedCombatIndex() == combat_index do
		sleep()
	end
	local result = IsHeroAlive(hero)
	return result
end

Then, you can avoid passing control to another function and continue executing the current one.
