I'm pretty sure once you change ISP's, and you're using a new ISP, they won't let you use another providers IP. Unless you can manually change your IP to an IP of a different ISP.

Short answer, you cannot.
Long answer, money fixes everything, smack ISP people with enough money and they will comply. (could go well into 6 or 7 figures though)
