I wouldn't think there would be much of a market for a "semi-custom " Savage. Pretty much anyone who knows right from left can do about anything there is to do to a Savage themselves without paying a gunsmith to do it and waiting however long the wait is these days. I personally like Savage rifles and fool around with them quite a bit but IMHO they lack the aesthetics of a Mauser or pre '64 M70 or even a dolled up Remington. Just my $.02 and yes, you will need an FFL and a tax number.
