Move melee heavy swing to secondary fire (option?)

I would like to see a change (or an option?) to have heavy swing on the same button as secondary fire/change fire mode, and at the same time also move block/parry to the same button as iron sights.

Coming from KF1, I'm used to a more powerful attack being on the secondary fire button for melee weapons and a few others, like the hunting shotgun. At the moment, I instinctively hit the secondary fire button and end up bringing up the weapon to guard, fruitlessly. It really feels like the secondary attack of melee weapons should be on the secondary attack button.

Additionally, it makes perfect sense to have the block/parry command share the same button as iron sights because you won't be using iron sights with a melee weapon, and you won't be blocking with a ranged weapon (unless I'm missing something).

I'll still play the game and enjoy it without this change/option, but the melee controls would be more intuitive and make more logical sense if these were swapped from how they are now. (More personally, it would make the game directly easier for me to control using my current control scheme for FPS games.)
