Help me with my Cyc

Hi guys, so I am working on building a Cyc for a production. I would be painting a 22x13' muslin drop white. Then lighting it with 5 or 6 ADJ Mega Bar RGBA 42" fixtures from below and 3-5 ADJ MegaPAR Profile fixtures from our only electrics pipe (hanging about 6ft downstage of the cyc drop. Will this provide enough light? What difficulties do you expect I will run into? This is my first time lighting a cyc and unfortunately have no budget for additional fixtures or drops.
