So long as it is a .361-ish Bullet, one ought to be good to go, so long as we are only talking about the Bullet itself, anyway..!

Sort of like shooting a 22 short in a 22 Long cylinder or even a 38 special in a 357 Mag cylinder.

No...
.22 Short, .22 Long Rifle, these are heeled, outside Lube Bullets, and in a Revolver, the Cylinder is bored straight through, no 'step'. The Bullets are the same diameter as the Cartridge Case.
.38 S & W is an inside Lube Bullet, and Cylinders meant for it, have the 'step' between Cylinder Chamber, and, Cylinder Bore.
.38 S & W, .38 - 44, the Bullets are the diameter of the inside of the Cartridge Case, being then that much smaller than the outside diameter of the Cartridge case.
Revolvers meant for Outside Lube, 'Heeled' Bullets, where the Bullet is same diameter as the cartridge Case is, their Cylinders are bored "Straight Through" and no problem to fire 'short', 'medium' or 'long' Cartridges, since the Cylinder Bore and Bullet Diameter ( at least in theory ) are the same, so there is no Bullet Jump or remarkable 'Blow By' of Gasses.

Sounds like another range challenge to me. I’ll put it on my list.
In fact I will load some 38 S&W rounds in full black powder and try them in comparison to my full loads already loaded. So we’ll see.

In the .38 - 44, the Cylinder has only the Chamber, no Bore...and, the 'full length' Cartridge Case itself, assumes the role of Cylinder Bore.
Your .38 - 44 Cylinder Bores are likely about .384 ID...a usual .38 S&W Bullet tends to be about .360...some may be .361...off the shelf ones any more are likely .358.
Assuming your .38 S & W Bullets are say, .360, then this leaves about .024 of an inch play for some really nasty Blow-By of Gasses, tilting of the Bullet, and the Bullet having no support for it's travel from the end of the short .38 S&W Cartridge Case, on to leaving the Cylinder.
You would get a "Bang", but all else would be a mess, and you will be inviting Leading as well as terrible accuracy.
Revolvers intended for outside Lube Cartridges ( which can then do fine with short, medium or long Cartridges, when such exist for them, and when their Cylinder lengths can accept the longer ones ) are a different Balllgame from those meant for inside Lube..!
