I answered in the other thread. It depends on which Office you want to pray.
Roman pre-Vatican II
Monastic pre-Vatican II
Monastic post-Vatican II (same psalm schema but incorporating changes to the liturgical year, monastic calendar, same collects as LOTH, etc.)
The Liturgy of the Hours already has all that is needed: the Office of Readings is intended to be said at any time but is inspired from the Night Office and can be used as such.
