Weapon Modification / Transformation

[High Mage Vivi]

What I want Is to have several 'Slots' on EACH weapon.
'Mana' can be equipped to each slot.
Each type of mana adds to a different stat:
White Mana : + 1 Def
Black Mana : + 1 Str
Omni Mana : + 1 Mag
Nega Mana : + 1 All

When A cirtain Combination of mana is equipped to the weapon It becomes something else e.g.

Bronze Sword + (W, W, W, W) = Rune Blade
Bronze Sword + (B, B, B, W) = Flamethongue
Bronze Sword + (B, B, B, O) = Aqua Edge
Bronze Sword + (B, B, W, W) = Glacial Sabre
Bronze Sword + (B, B, O, O) = Bolt Edge
Bronze Sword + (N, N, N, N) = Blood Sword

I don't know if this is possible, So please help me!
