Do you already have the conversion? If you don't, don't bother, you can use the CFL's for the beginning stages (clones sprouts) and then have a seperate area for flowering with an HPS.

If you already have it, use the CFL's till the clones are rooted and then put them under the MH until it's time to switch to 12/12, then introduce the HPS. Simple as pie.
