Maneuvers for other combat skills., Why limit it to Unarmed/Martial Arts? Options

[Catsnightmare]

Under the Martial Arts rules in the CC, you can buy certain Maneuvers according to your level of skill in your particular Martial Art/Unarmed Combat style.
Why not have the option of purchasing maneuvers with other melee combat skills, clubs, edged weapons, etc. Hell even for ranged weapons too, Pistols, Projectile Weapons, Thrown Weapons.

Some of the existing Maneuvers would port over well to melee weapons, Multi-Strike, Vicious Blow, Whirling. Some of the ones I thought up include.

Melee Weapon Maneuvers
Quick-Draw The quick-draw maneuver allows the character to use quick drawing rules with melee weapons, but only weapons of the skill the maneuver is purchased for. I.E. you get quickdraw for the Clubs skill thus you can only quick draw those types of weapons.

Firearm Maneuvers
Speed-draw This maneuver can only be purchased for the Pistol skill. Using this maneuver when the character makes a quickdraw test, the number of successes from the test is added to the characters initiative. The character only gets this initiative bonus under certain conditions. They only get this bonus for the first combat turn, (thus no silly-assed "I reholster my gun and quickdraw again." for faster initiative munchkinism), and they must use only the pistol to attack, any melee attack (including counterattcking) and the char loses the speed-draw bonus for the rest of the turn.

I'll add some of my other ideas as time permits. I'm also open to suggestions, constructive criticism and ideas.
