Stash - have you solved your problem yet?
It sounds to me like the Crumpler 6MDH is the bag you need, but if you can't get it where you live, have you tried to get it from Adorama? I have bought quite a lot of stuff from them, from lenses to Think Tank stuff, and although the UPS costs are a bit high, it still works out cheaper than buying locally. And of course, if you can't buy it locally, then there ain't many options...
Adorama have always been very quick, no problems.
And no - I don't work for them...
