What comes to my mind when I hear Feynman integrals is work of my colleague in his collaboration with DESY. https://risc.jku.at/m/carsten-schneider/ As far as I understand it, Feynman integrals can be transformed into a summation problem, then simplified by Schneider's Mathematica package Sigma. Obviously, some physicists find that very useful. Not sure whether that is similar to what you are after, but of course ther would be a Mathematica license issue as you say. If you feel that FriCAS can in principle do the job for you, then keep on asking about whatever blocks your way in implementing you problem. I am a bit concerned about your wish to solve the master integrals numerically. I'm not quite sure whether FriCAS is the best and fastest tool for that, but perhaps I just don't understand enough of the details of your problem. Anyway, good luck with your endeavour.
