So far, so good.

You are using the wrong words but I think I follow.

You don't want to emulate the image. That's like saying you have a
car, and you want to drive the tarmac.

You would need to emulate a RasPi. That's what's needed to run a RasPi OS image.

But I don't think there is one. It's a very complex little machine.
It's not easy.

I could be wrong but AFAIK you can't.

No, it won't.

Then you need a whole computer emulator. The RasPi is not a PC and is
nothing like a PC. It is not at all a typical ARM computer, either, as
Ogra says.

Not gonna happen.

It won't.

You can emulate a faily vanilla Arm setup in QEMU but it won't run on
a Pi, and a Pi OS won't run on it.

Why would you think that?  On what basis?

You can't run an Arm OS intended for a normal ARM computer, say an Ampere box:

On a Pi.

Any more than you can take Windows 95 and run it on an Intel Mac. Or
Acorn RISC OS from 1987 and run it on an M1 Mac.
