Normal Luk Versus Lukless; When do they surpass?

Wouldn't normal-LUK Mages (assuming they have a capped base LUK) benefit enough from:

• Zakum helmets
  
• "Egg'd" Horntail necklaces
  
• MW 30
  
• Mage equipment
  
• Scrolled wedding ring (each slot adds 1 of each stat)
  

for their lesser base INT to not matter at all? As long as they use all of their LUK towards something (like that level 163 staff), I don't see how it could. Then again, I don't know what a fully-upgraded Horntail necklace adds, so it might be possible for LUKless to be able to equip high-leveled LUK staves using the LUK they gain from equips like those.
