Surprising Power Drop, Although Mapped.

Thats true, its called Turbo Coking. And in some premium cars they have special cooling measures (like water? perhaps) which solve this issue to some extent. Also one can opt for a turbo timer.

Is it possible to replace VGT in Linea with a FGT of Punto?

I idle for 45 seconds and after every drive when I enter my colony and my parking area I drive at lowest possible revs... And then idling.. Since quite some time

I don't think so.

Also it can kill the drivability of Linea in lower gears if such a mod is made possible. It will also need ECU mods (maps?) and also the peak power will comedown from the rated/stated 90hp.

also when the car is in neutral its a good practice to press the clutch and then start the engine.
