A new villager

I propose the idea of a new villager. This villager could be named a stablehand and it trades emeralds (obviously) leads, golden apples, saddles, and horse armor. The latter trades would be more advanced seeing as saddles and horse armor are pretty good loot. It would do trades in exchange for sugar, apples, string, leather (because if saddles were craft able they would be crafted with leather most definitely), and ores such as iron or gold (this is because horse armor is always named with ores or leather). I haven't fully worked out what the job block could be but I'd say it could be something like a trough which when filled with hay, horses eat from it and gain health at a rate of 4 hearts per second until it's depleted.
