I'm planning something similar but as a road trip. This is an interesting idea though and if your cost calculations are fine then a better option I think. However, sure you sure that cost estimate is appropriate for such a long trip. A/C tickets can be quite expensive and traveling in regular coaches is a big pain. Also, did you take into account boarding/lodging/local transportation/rec stuff?
I'd like to know more about your plan so let me know
