I like it but I'm not sure it will work better or easier. One thing you will find is that you have more areas where the vapors are going to crystallize, like inside the hose, that you will have to scrape to make the recovery. That's not a big deal, but i'm just not sure you really gain anything with this setup, pretty as it is.
The method SWIP posted in the gakinator thread calls for sealing the container, but in a way that it can momentarily pop open if the pressure gets to great, and that happens from time to time. It doesn't stay open long, and the leakage isn't even noticable. It just vents the excess pressure then setlles back in a closed position. You would NOT want to seal it up where the pressure couldn't escape without breaking something unless you like explosions that send breoken glass flying everywhere.
Having said that, the method posted in the gakinator thread can be run without ice, however it works better with ice, and is less apt to pop open if ice is used. If SWIP were to try your setup, and he may, he will still use ice. (Just encourages things to go as they should.) One enhancement he might add would be to wrap the heating flask with aluminum foil, so that little condensation of the vapors would occur in areas where the crystals could fall back into the cooker.
The more I think about it, the better I like it. Nice work!
