Salve Regina - Hail Holy Queen

The following is the Hail Holy Queen prayer in Latin:

Salve Regína, Mater misericórdiae. Vita, dulcédo, et spes nostra, salve. Ad te clamámus éxsules filii Evae. Ad te suspirámus, geméntes et flentes in hac lacrimárum valle. Eia ergo, advocáta nostra, illos tuos misericórdes óculos ad nos convérte. Et Iesum, benedíctum fructum ventris tui, nobis post hoc exsílium osténde. O clemens, O pia, O dulcis Virgo Maria.  Amen. [1]

Being me who is seldom satisfied with what is normally excellent and accepted as excellent, I would like to add after "O dulcis" a comma, a space and these words:  "O sanctissima, inviolata, intemerata, O pulcherrima" before Virgo Maria. [2]

So this is my version:

Salve Regína, Mater misericórdiae. Vita, dulcédo, et spes nostra, salve. Ad te clamámus éxsules filii Evae. Ad te suspirámus, geméntes et flentes in hac lacrimárum valle. Eia ergo, advocáta nostra, illos tuos misericórdes óculos ad nos convérte. Et Iesum, benedíctum fructum ventris tui, nobis post hoc exsílium osténde. O clemens, O pia, O dulcis, O sanctissima, inviolata, intemerata, O pulcherrima Virgo Maria.  Amen.

[1] The best Latin pronunciation I have found for prayers in Latin on You-Tube is at https://www.youtube.com/watch?v=gM5dDgTn4w4.  The Hail Holy Queen prayer, Salve Regina, starts at about 2:27.
[2] GreenWhiteBlue of New York, a person who commented on these words on June 13, 2007, said, "I am assuming that this is a text referring to the Blessed Virgin Mary. The four adjectives mean 'most holy, inviolate, undefiled, most beautiful.'"
