You are probably using too many microphones. It sounds as though you are almost dismissing the most important microphones that you will be using and that is the stereo pair for the overall pickup.
If you get these in the right place, you won't need all those other microphones.
Whatever method you use for the stereo pair, the sound must be excellent from these microphones or your recording will not sound good.
Having said that, spot microphones can come in handy for certain vocalists that may need to be highlighted for solos, but you will want to delay the the signal from those microphones to align with the stereo pair.
