I think that sounds good.
Before coming to AA and finding out that I really needed to learn more about aquatic care, I always did my cycles w/o BB/seeded filter as I didn't even know what that was!
I started and ran several tanks that way, but since, I have set up several preparing the seeded stuff ahead of time and it has been flawless, as long as you start out slow on the bioload/adding fish my numbers were always very good.
If you have rocks/decorative stones you will be putting in you can add them to your existing tank too and they will start getting a little BB also.
