After considerable thought and a lot of internet searches, I've come to the conclusion that this would be a waste of everyone's time. The best I could do would be a half assed mess of a model and insult the membership of this board.
To quote one poster from another board, "it is not possible to convert Monogram's F4C to an F4B." Yes I will build it and dress it as "B", but I won't waste this campaigns participants time and their efforts with this build.
Phanken-Phantom will go quietly to to shelf.
Give me a day or two to come up with another entrant.
Thank you in advance for your understanding my withdrawal of this model. I did truly under estimate the degree of modifications need to pull this off.

Bob, you can delete this topic altogether if you choose to. I'll start a fresh one when I decide on what kit I'll enter.
