Attempting to run a DUAL pulley AC pump mite develope fan , water pump pulley, drive pulley to radiator, drive pulley to fan clearence problems or other clearence problems. Need to do at least a crude mock up to determine clearences and belt routings.
Take a look at these pics. Note the AC pump belt running close to fan. NOTE SPACER BETWEEN FAN AND water puMP pulley. Not clear in pic but AC belt will ever so sloightly rubb pump pulley if i gets slightly loose.
Since u are adding a SECOND belt the belt MUST set forward of the belt in the pic of my set up. Unless u are completely rerouting ALL other belts in some way.

As for the 4 row pulley Patgreen pictured above it just mite work but getting it centered and dogged to the harmonic balancer along with other potential clearence problems just mite be a "time and material" cost basis project and often such attempts are beyond either average automotive tech's skill level and/or beyond their interest level to do so.
