Without the ducting, you will not be utilizing the benefits of larger radiator. As far as the grill, you don't need to remove it, you just need to open up some sealed honeycomb cells with a dremel (I did lower grill only and it seemed to have helped quite a bit). However, once you do it, you will increase under hood pressures and front end lift, so a hood louver becomes highly recommended and very beneficial.I think @Flyhalf runs the same Mishimoto radiator so there should be an improvement over stock. My other option would be Fludyne 3 pass but they have supply chain issues and harder to ship to Europe. I really try to not go full blown race car though which is the reason I don't want grill delete / GT4 hood.
In reality, hood louver is the only thing from all of that that is going to make your car a bit less daily practical, but even that can be addressed.
PS I guess you could still skip the louvers and do hood pins, at least you will know that your hood won't fly away. Mach1's have quite a bit larger front grilles surface and same hood as regular GT. It seems to be fine.
