I don't know if the process is the same, but for me to switch from a "public" plan to an everything plus referral plan, I had to wait until my contract expired, port my number to a pre-paid type service (anything but Virgin or Boost), then port my number back to Sprint to a new account for the Everything Plus plan. It was an absolute pain. I don't know if going the opposite direction will be as bad though. I was told by numerous people I talked to online, at telesales and at employee telesales that my number could not be ported from one Sprint account to a new Sprint account.
