Landing with the TGP could be catastrophic. The widest field of view is exceptionally zoomed in compared to what you see out of the cockpit, or the "naked eye." All the movements of the aircraft would be exaggerated on the MFD.
ILS is a precision approach due to the glideslope indicator and landings in IMC is exactly what it is designed to assist with accomplishing. Landing with zero/zero is not advised for any aircraft, find an alternate as advised above. The lateral guide gets wonky near the airport, so don't chase the needle. Your best bet is to make gentle adjustments until you see the runway environment then make a landing or even circle to land if you're too high over the threshold.
A good set of approach plates for each airport would be nice; I'm not sure if these have been made, I haven't searched. It would help with the minimum altitudes on approach and give addtional terrain data and maybe a good circle to land altitude.
