I don't think that FeynCalc is the right tool for that, unless
you exactly know what you are doing and how you want to use it.
There are more automatic frameworks for such studies, i.e.
FormCalc, GoSam or MadGraph, which already contain codes for
deriving Feynman diagrams and doing the numerics. So I would look
into that direction.
