Śrī Matre Namaḥ
You can certainly adapt the recitation of the Śrī Sūktaṃ to fit your schedule. The essence of any sadhana lies in the intention, dedication, and regularity of your practice.
Do remember, however, that the fruits of any spiritual endeavor are not guaranteed within a specific timeframe. While the initial sadhana is suggested for a minimum of 44 days, or one mandala, you may need to continue beyond this period.
