If you dont want the centre icon then yes it would be better not to have leedroid as I think the modded rosie would cause the rom to either bootloop or sense to crash. I dont think it will work.
What you could do is backup your current rom, then flash the zip in recovery and see if it boots. Then if it doesn't restore your backup.
