Music: Memorare chant

I have absolutely no training whatsoever in chant, so I'm sure I'm going to butcher this project (when I get around to it), but I have half a mind to compose a Gregorian chant of the Memorare. I think it would be Hypolydian (Mode VI) which is classified as "devout" (D'Arezzo), "pious" (Fulda), and "tearful and pious" (Espinoza).

MEMORARE, O piissima Virgo Maria,
non esse auditum a saeculo, quemquam ad tua currentem praesidia,
tua implorantem auxilia, tua petentem suffragia,
esse derelictum.
Ego tali animatus confidentia,
ad te, Virgo Virginum, Mater, curro,
ad te venio, coram te gemens peccator assisto.
Noli, Mater Verbi,
verba mea despicere;
sed audi propitia et exaudi.
Amen.
