Tejas is smallest fighter in the world, so is it possible to just upgrade its entire body to make it stealthy to quickly get stealth capability as Tejas Mk1B?
The internals remains the same. Just whatever stealth is possible with outside can be added.
Delta wing can be slightly changed to Semi-flying wing type of design.
The engine intake and exhaust can be better concealed.
Even if it is halfass stealth, it would be far better than what we have got, and Tejas already has the advantage of being too small.
