this is so nice for making farms ,thanks :)

Can u add Pillager spawn eggs?? For one egg and a crossbow :D

for my first question, is there any way to change the egg recipes for blazes to like 3 stacks of 64 blaze rods, all the others to like full stacks of leather, bones, etc, and are you going to add in iron golems? if so would it be possible to make it a stack of iron blocks

are you going to update it on 1.14? or should i ask when you going to update it

If the spawner works and you are able to change the spawner into any mob you want, then that recipe is way too cheap, you could just make a ton of them and the excitement and fun in finding a spawner or building a farm is gone. I understand that this might simply be for lazy sake, but I think a more balanced recipe would be to replace the obsidian with rarer blocks, maybe soulsand or mossy cobblestone. and replace the diamond with a netherstar, heart of the sea, or something else you can't mine a ton of.
Just a note from me.

it would be nice if u add silverfish and endermite

c'est compatible 1.13 ?

The idea of this is really good, but i think the crafting recipes for the spawn eggs are too simple and makes it too easy to obtain, I suggest modifying the recipes by adding another component to make it more difficult, like a diamond, or maybe even something like a potion of regeneration, similar to the zombie villager "ritual" thing.
