I agree with Monarcheon. but I really admire you using alternate tuning, and a bow.. This certainly deserves more exploration.. There have been some guitarists who use different guitar string tunings, (and then have to modify their playing techniques), but it can create something unique..
There was a device in the 60's or 70's called the 'Ebow'.. It was this small thing the guitarist held in their hand (not sure if it was a spinning wheel or what).. But it would give you a bowling technique, great for the guitarist to make these kind of atmospheric pads.. But the bow, never ran out, The string/strings would continuously resonate, as you moved it over the strings.
Great avenue to pursue..
