It is better to split up economic activity in phases of geographical area.
The usual anti national stakeholder have Strategically placed themselves near coasts, in area rich with natural resources and areas with demographic instability.
Everyone but the India RW ecosystem has Brains to recognise this
Raw material and parts/subcomponent assemblies manufactured in the North.
Final assembly and export done in the South/Coastal regions with good ports.
Incentives must be provided for specific sectors to invest in certain cities/districts in the North, like for a state as big as UP 5 cities/districts can be allotted.
This will happen eventually, coast will get expensive, so manufacturing will have to move in-land.
Riverine transport through Ganga river is also a fine idea.
