Only one way to find out! They're always creating new fabrics as well...the one I ripped was 0.8 oz taffeta (not ripstop or sil, so either of those would obviously increase the strength a bit). There are already some cuben underquilts out there...can get a bit lighter than that, but not much if you use the lightest weights.
So get in the game and make an underquilt w/ .25 oz! I'll test it for you...
“Republics are created by the virtue, public spirit, and intelligence of the citizens. They fall when the wise are banished from the public councils because they dare to be honest, and the profligate are rewarded because they flatter the people, in order to betray them.” ~Judge Joseph Story
