Re-quoted for truth. Going from .125 all the way down to .032 is a big change. You may be satisfied with .062 (1/16"), as this cuts the weight in half. If you do change alloys, you gain 40% in yield strength, so it's a net loss of 30% of the original strength for 50% of the weight. Might be worth it.
