The equipments that you could switch to have luk with no loss of stat are:
-Overall (only useful for going from the 120 luk to 165 luk)
-Shoes (no scroll for shoes for int or luk so you can just choose the shoes that give more luk and maker them preferrably with luk crystals, I'd stick with the lvl 90 shoes since they have matt, try to chaos them in the future)
-Hat (sort of since there are no scrolls for headgear for luk you are going to scroll these for INT anyway, just try to find one that has better LUK than INT)
Capes are not ok (you'd want to chaos a purple cape, otherwise you can scroll for luk if you don't feel like chaosing), gloves, earrings and shields gain matt from the scrolls so they are not an option.
Of course, try makering all your gear with the best possible of wisdom/luk crystals.
