I'm sure this has been tried over the years, but please enlighten me.

The 4 inboard head bolt / head stud positions, can you make a wedge block accept Hemi heads ?

I know the main caps won't be the same.

Isn't the only really tricky part the 4 head bolt mounts?

Is it possible, just not feasible or practical ?

Even the motor mounts you can get around.
