i cant think of a Scandium tubed bmx frame before this,
always wondered if it would work!  fair play to supercross for giving it a whirl 

i had my ti reaper down to 17lb  so with carbon cranks/forks, 28 spoke fr wheel, ti bolts etc, it would be do-able 

you'd be left with a very "waffery", nervous bike though 

calling it a "trails frame" is a bit optimistic though
