i think it is a good idea but i would lean more toward using just the spindles with some grease in them and a block off plate. i have done something similar but on a much smaller scale when i was 16. i pulled the rear spindles off of an old k car i got for parts. bolted them to a piece of heavy angle iron welded to the ends of a heavy pipe so it lowers the center of the axle. it was used for a 4x8 utility trailer but i have had well over a ton on it with no problem. even lowered a gutted car body onto it to make a scrap run.
like mentioned it has been done, at first i was just going to use an old axle but talking with a few guys decided i didnt want the extra weight and spinning gears sucking up some of my go power and fuel. might not matter much at all on a big trailer but a utility trailer like i had it would about double the weight.
