I’d say you could probably +P your 35 Remington loads – but I always worry about them falling into the wrong hands or getting used in a 35 Remington auto loader or older steel gun. Generally it’s just not good practice. Converting to 356 which is a jump of 25% in pressure is more of an issue to find out if there is much difference in the actual frame/bolt of the guns marlin sold – like 38 spl and 357 are the same frame and cylinder but different heat treatments/steels.
As to 358 win conversion – I’d say no – I’d look for a used Savage 99, Winchester 88, Sako FinnWolf to rebore/rebarrel
or just buy a Browning BLR in 358.
