Sounds OK to me. As long as the caloused cuttings are about 2 inches into the soil and the roots have some room beneath them to grow they will start just fine.
A couple of years ago I got an old metal rain gutter, you know - about four inches wide and four inches deep and 20 foot long. I lined the cuttings up in soil about 3 inches apart just like soldiers, tilted it a bit so the water drained out the end. Cuttings rooted just fine and got moved to pots when ready.
