First problem will be the route.. you will need to come through Myanmar and thats not very safe. Also, am not sure whether you will be allowed in at the Indian Border Checkposts there
Here's the complete road route you will have to take. It will take you
76 hours for the 4,905 km journey. I am afraid, its not the ideal route one should take. Purnendu is right, Burma is currently not safe specially on the Bangladeshi border.
