Happy ghast rehabilitation

Hello Mojang. I love your work! I had a suggestion to the new happy ghasts, I was thinking of the achievement for bringing a ghast to the overworld and killing it and with the lore from the new happy ghast it made me sad. What if the nether ghasts could be rehabilitated? By bringing them into the overworld they would gradually change from the aggressive ghasts to a calmer happy ghast eventually being tamed. I thought this would be a beautiful way to expand the lore and make for an interesting alternative to getting happy ghasts. Well I don’t expect the removal of the achievement an uneasy alliance I do think it’d be interesting to also add one for rehabilitating ghasts. Thank you for reading
