How interchangable are these? Would 9mm bullets work accurately in a 357 caliber?

wasn't there an SP101 once upon a time which was capable of doing .357 along with 9mm in moon clips?

depending on your dies you may find that the 9mm do not remain in place well. The neck tension will be minimal, and may be insufficient to properlyy hold the bullet. Furthermore, there is no good crimp groove on a 9mm bullet. And 357 or 38 dies are typically roll crimp instead of taper crimp. You'd be trying to roll crimp an undersized projectile with no crimp groove AND little neck tension. Good luck getting a decent consistent overall length.

I would expect that accuracy would not be stellar. Using lead bullets? Expect severe leading.

Not that I am aware of. Ruger did build a 9mm sp101, but it was a 9mm. Oddly, some of the reviews I read reported higher velocities from the sp101 than from a beretta.

There was a revolver in the late 80's early 90's called the medusa. Supposedly it would shoot anything from .380 all the 9's (except makarov and the whole 38 realm of cartridges. Around 3 dozen IIRC. It was very expensive and not exactly common.

No commercial 9mm bullet will fit properly due to the size difference many others have stated.

However, if you cast your own, I found that the Lee 356-120-TC mold will cast .357-.358 using wheel weights, so you can simply pan lube them ("Barry Darr" mix of 1lb paraffin, 1lb vaseline, 2tbsp STP) and they're ready to go.
Accuracy is good for a light bullet and the truncated cone seems to help them drop from a speed loader into the cylinder. I've just not worked up a quality load for them due to having several coffee cans of 158gr SWCs that I cast last winter

Ruger still make the BlackHawk in 357 that comes with the 9mm conversion cylinder no moon clips needed it head spaces on the case mouth the same as the semi auto I've had one for almost 30 years and it shoots the 9mm cartridge just as accurately as the 38/357 side. I've shot factory ammo and reload with all bullet types with great success. Haven't tried shooting 9mm bullets in the 38/357 case though.

Groups fired in the Ruger using the 9mm conversion cylinder.

Ruger made a single action Blackhawk that came with 2 clynders. 9mm and 38/357.
