Hobbo, will the car be stock or modified/custom? If 'stock', then there may be a good argument for keeping it exactly that - stock.. (including its original colours)
Otherwise, go for it; it's your car, your call!
Personally, I prefer the FC side mouldings and colour schemes (any original colours or whatever you want)
However, IMHO the FE grille and indicators look far better than the FC equivalents...
So if it's to be a 'modified' or 'custom' car, how about a hybrid FE/FC?
Keep in mind that what others think is really of no consequence - you should possibly be only concerned about keeping two people happy; you and Mrs Hobbo!
Good luck which ever way you go, and please keep us informed
cheers, jack
