A boxed frame will still flex, be it steel or aluminum. Here's a thought
to ponder. I know some guys take small wire or buzz box welders out on
the trail. It's sometimes possible to patch a cracked frame enough to
get home. But that's steel. How many guys take a TIG welder out on the
trail?

But hey, give it a go. Nothing like empirical testing... G
