Loading a .355 in 38 might work if you used a 9mm expander - with a .357 expander you won't have enough neck tension and will get sketchy ignition.
The other way around, .357 in 9mm, is used a lot with cast bullets in loose barrels. Plated can probably be treated like cast. Jacketed would be very dependant on jacket thickness and profile.
FWIW, I've loaded 9mm/.380 bullets in .38 Special regularly. Recovered bullets from my revolver mic at .352" so I think the .355" bullets are just fine.
The 95g FMJRN have ample power for most uses, unless you hit a pepper-popper at the absolute base. Can't say I've ever had a .355" bullet yaw and hit the paper sideways..
9mm HST bullets, GDHPs, etc., all work just fine in my .38 Special and .357 Magnum.
You can always run your .357"/.358" bullets through a sizer die, if you want to use the in a 9mm, but bullet profiles may not be optimum.
