I would, but I don't think it'd be realistic to have the kit, unless it was a $300 or $200 or possibly $100 donator perk. I think that since these items are very rare and special, they should stay that way. I think that if you did decide to do it, it'd have to be a once a week or once avery few days kit. I still think it's a great idea, but that's my opinion.
I think we should have different egg kits availible, like a Chicken spawn egg could be a 20 dollar donator, but a ghast, mooshroom or blaze should definitely be 75+ dollars
