Since there is not any mob merge plugin which does what I wanted, I made this...

This plugin allows nearby living entities to be merged into one entity.  By doing this merging, you can significantly reduce the number of living entities (mobs) on your server -> reduce lags.

Some claimed that you can dupe an item by letting the merged mob to pickup an item you wish to dupe.  The below video tried to re-produce this claim but we could not do such.  Mobs (Husk) were spawned using
/summon husk ~ ~ ~ {CanPickUpLoot:1b,HandItems:[{id:"stone",Count:1b}],HandDropChances:[0f,0f]}
