Can we say the "Adir bamarom" prayer after the prayer which we say instead of "Birkat Kohanim"?

Question

Extracted from here:

The prevailing custom in the Diaspora to relegate the Birkat Kohanim to the major holidays. After Birkat Kohanim, the congregation silently recites the short Adir bamarom prayer.

When Birkat Kohanim is not performed, the chazzan recites the short prayer, in lieu of Birkat Kohanim, "Our G d and G d of our fathers, bless us with the threefold blessing written in the Torah by Moses Your servant, and pronounced by Aaron and his sons the Kohanim… [and the prayer concludes with the text of the Priestly Birkat Blessing]."

Is there a source for saying the Adir bamarom prayer after the in lieu prayer?

Answer 1

Sure! The Rama recommends saying it every day (for those who don't say the full Birkat Kohanim every day) after the in lieu prayer. Shulchan Aruch OC 130:1
