I can't see any grounding in reality for doing that personally.
There might be the argument for moving to a short acting opiate for a month or so but finding a doctor who will do this for you is going to be very hard. Technically, you can use the short acting opiate to carry you through the long bupe withdrawal period, and then only deal with the shorter withdrawal period of the short acting opiate.
Rightly, moving back to short acting opiates is highlighted as a risk in that a drug's duration tends to be inversely related to it's abuse potential. Whilst it may help with the physical withdrawal, it's a very clear psychological risk that is a big red flag for most doctors.
I haven't seen any argument that holds water for bunging a weeks worth of methadone on the end of a period of bupe use to help with detox. That doesn't mean it doesn't exist though.
