I like the review tbird. I doubt they will, but I would love to see BH come out with a 2nd run with those changes that you mentioned. Honestly the water bottle and lack of "real" carry handle is the only thing that has stopped me from buying one of these.
Another thing that might be nice would be to have the buckles on the sides to hook to the front of the tongue to keep it up similar to how you were trying to do with the zippers. Something like that one could always add later if they knew someone that could do some basic sewing.
