I am 87 and have faced the same problem. Have R3, R5 and lenses, but just too much for travel. Admit the OM-1 has better specs, but I went to the OM-D-Mark III which has most of the OM-1 capability but is lighter still and mainly use 12-200 lens. I find it great for travel! If you have any interest in Macro, the 60MM Macro for it is incredibly small and light as are the other lenses relatively speaking.
The RX10/100 does away with all extra lenses. If you truly want to shed considerable size and weight and ENJOY the trip, the Sony RX series is an excellent option. But, if you don't mind carrying and buying extra/bigger lenses or you plan on making/selling larger prints then M4/3 may be a better option.....
