I would cycle it with the top two leafs. You can droop out a leaf pack with all the leafs on it but bottoming it out will be tough. WIth just the two leafs all you need is a couple people to sit on it.
Use only the main leaf and make a block to replace the lost height of the rest of the removed leafs...usually the block will be about 2 - 3 inches. This way you have easy cycling with only jack and have somebody step on the housing for full droop. Watch your brakelines!
