The SSPX give a rather beautiful Novena for the election of the Sovereign Pontiff, which you can find here. It is a little late in the day to post this but still may be of use.
Novena for the election of the Sovereign Pontiff – March 2013 (1st to 9th)
Veni Creator Spiritus
Come, Holy Ghost, Creator, come. From thy bright heavenly throne! Come, take possession of our souls. And make them all Thine Own!
Thou who art called the Paraclete, Best gift of God above, The Living Spring, The Living Fire, Sweet Unction, and True Love!
Thou who are sevenfold in Thy grace, Finger of God’s right hand,
His Promise, teaching little ones
To speak and understand!
O guide our minds with thy blest light, With love our hearts inflame, And with thy strength, which ne’er decays, Confirm our mortal frame.
Far from us drive our hellish foe, True peace unto us bring, And through all perils guide us safe Beneath thy sacred wing.
Through Thee may we the Father know, Through Thee the Eternal Son, And Thee the Spirit of them both Thrice blessed Three in One.
Now to the Father, and the Son Who rose from death, be glory given, With Thee, O holy Comforter, Henceforth by all in earth and heaven. Amen.
V/ Send forth Thy Spirit, and they shall be created:
R/ An Thou shalt renew the face of the earth.

O Lord, with suppliant humility, we entreat Thee, that in Thy boundless mercy Thou wouldst grant the most holy Roman Church a pontiff, who by his zeal for us, may be pleasing to Thee, and by his good government may ever be honoured by Thy people for the glory of Thy name. Through Our Lord Jesus Christ.
V/ Most Sorrowful and Immaculate Heart of Mary,
R/ pray for us who have recourse to Thee!
V/ Saint Pie V.
R/ pray for us.
V/ Saint Pie X.
