After watching the Anolis version of Cemetery Without Crosses and their Django Kill reuse, I thought how interesting it would be if I had could swap scores with different spaghettis. Seeing how different scores worked with different films. Here is some possibilites.
His Name was Holy Ghost score with Taste of Vengeance
Return of Ringo score with Drummer of Vengeance
Companeros score with Big Gundown (?)
Once Upon a Time in the West score with The Forgotten Pistolero
