No, Gillionaire only stacks once for a single double Gil bonus. If you want an even better method of getting Gil I suggest fighting One-Eye in the Arena over and over. Once you start hitting him for 99999 damage, and with enough Agility, you can kill him off quite easily and quickly, gaining Triple AP equipment which can sell for up to 60k or so.
