There's nothing wrong at all with trying new designs - who knows?!? you could have the next blichman product rolling around your noggin. Don't sweat it being kicked to death.
As far as the SS Screen. I'm not sure how rigid it is exactly, but you could reinforce by placing small SS bolts (i.e.8/32 x 1/2") through the screen every 3" - 4" square to form a infrastructure to support the screen off the bottom of the tun. Just secure them on the underside with some SS nuts.
perhaps a line of single hop IPA's - there's so many new hops out there!!!
