Split/Baby Golems

What if Golems were nerfed in a big way to make them more/less useful. Making them worth their value. Bc right now 4 iron blocks (9 ingots each) and a pumpkin for an iron golem that dies easily by skeletons and hordes is a waste of 36 ingots. 

My idea for iron golems is to nerf them to be given more strength and speed but a slight decrease in health. But also be given the ability to split into 2 smaller golems that is 50% smaller, 2x-4x faster then the regular golem and have half strength but same or less health.

They could also have an alternate nerf to be the same as above but split into golems that is 25% smaller then the original but have 25% less health, strength but given 1.5-2x more speed and when those golems dies they split into 2 seperate golems giving them 3x-4x speed, decreased health and strength.
