You can follow the spirituality of a particular order, but don’t expect to turn the rectory into a cloister.
For instance:
As a diocesan priest, you may use Franciscan spirituality as a part of your personal spirituality, or you may try to take some parts of Benedictine spirituality and apply them to your own spiritual life.
It would not be good, however, if you demanded to stick to a rigid horarium put this in front of the care of your parishioners.
I would recommend you spend some time in discernment and decide which is best for you, and learn the difference between a vocation to the religious life and a vocation to the secular priesthood.
That being said, I’d also recommend for you to look into some religious orders that have pastoral apostolates. The Redemptorists and the Oblates of the Virgin Mary come to mind.
