I'm planning to do something similar but I'm going to test it out on the smaller size first.
Do a search for Kossel on Thingiverse and you can find some carriers that do not require a looped belt. The place I'm getting my printed parts from (Maker Geek) agreed to make me a few custom items from thingiverse as part of my order for an additional fee. In particular this should help and it's what I'm trying. I figure that by removing the linear rails it will be much easier to scale vertically and I just liked the clean design of the open loop belt part.
