Can the VoiceLive Rack be used in a Mixing Board’s Effects Loop to Double Vocals on Multiple Channels?

Can the VoiceLive Rack be used in a mixing board’s Effects Loop to double vocals on multiple channels? (So the mics would be in different channels of the board, with varied send amounts on each channel, going to the VoiceLive Rack. Then the Lead Mute would be turned OFF on the unit. (Or does that only affect the lead vocal when a mic is plugged in directly to the VoiceLive Rack?)
