I would skip trying the potters --- tried it, it was awful, too similarly colored.
I did it with the venustus, both are shy angels, so that works well in their favor. The multicolor might work too (( I currently have a multicolor with a coral beauty and flame in my 65 )).
Would suggest using an acclimation box -- for up to a week -- goes a long way towards getting them to get along.
This is an older video (( lost the golden to the pink skunk clowns and their S. haddoni )), but this grouping was together for 6 months without issues. Tank was a 36" 58 gallon.
