On the question of adding a 1/2 inch spacer, that is a maybe.
The answer is yes if the spring is on top of the axle tube. If this is the case you can add a block and longer U bolts on the low side to level it out.
The answer is no to maybe if the spring is under the axle tube. With the spring under the axle tube you would have to put the block under the high side to lower the trailer by 1/2 inch on that side.
Be aware that spacer blocks for leaf springs are not just square flat blocks. Leaf spring packs have a bolt that goes vertically through the center of the pack. The spring pad on the axle tube has a hole in the center for this bolt head to sit in and center the spring. The lift block needs a hole on one side to accommodate the bolt head, and a bump on the opposite to drop down into the hole in the axle tube plate.
You might find it hard to locate a lift block that is only 1/2 inch tall. Although now that I think about it; If the center bolt has excess threads you could drill a hole through the center of a 1/2 inch plate and put it into the spring pack at the bottom using the existing bolt to hold it all together. That would eliminate the need to find a manufactured spacer with the bump and hole and just use a piece of flat steel.
