I did the power upgrade that you are thinking about doing with an older F-7 A unit. Read the instruction sheet from Bachmann and you should be able do the upgrade yourself.
The one problem I had was with the step-ladders mounting hole needing to be drilled out by one/sixtyfourth of an inch, usually one drill bit size higher.
The other problem was with the motor strength of the new upgrade kit being stronger than the older Williams motors in my older F-7 A unit. The new kit is about 10% stronger than the motors from about 15 years ago. If you are doing a newer Williams or a Williams by Bachmann, I don't think this will be a problem.
