Modify current modded villagers

I am solving an issue when I would like to change a stacksize for emeralds, but some trades (forestry villager) cost 64 emeralds so they wont be functioning any more. I was hoping your mod can help, but I didn't figured out how.

Can I figure somehow how to change behavior of nonvanilla villager?
Can I change all villagers to use other currency than emeralds? I tried to switch it to morebees:emeraldFraagment but nothing happend.

Thanks in advance.

Assuming that the villagers from other mods are simply new professions for the vanilla villager (most are, but I'm not certain about Forestry) then yes, that should work fine. You just need the registry name of the new villager profession, and you add that to the trade file. Check out the adding and removing trades section on the wiki.
