If you mean grant "Bi-Ritual Faculties" It can safely be assumed the answer is yes, however, you are more likely to see bi-ritual faculties granted a Latin Rite Priest because of numbers.
It is in fact a not an uncommon practice.
The most prominent Bi-Ritual Priest is Fr. Mitch Pacwa, though he may have been ordained with Latin Rite Faculties and had them extended to the Maronite Rite.
As a reminder however, many Eastern Rite Parishes have not adopted the custom of Daily Liturgy so many married Eastern Rite Priests have the ability to hold down secular jobs if they choose.....at least in this part of the world.
Interesting.
I should have scrolled down before posting my response to kawaii. Sorry for not including both of you.
