would a portable (NX) GTAV be huge?

GTA on any system would be huge.

Then why they never released any gta on nintendo systems ?  

They released two:

-GTA Advance (GBA). Nobody remembers this one, at all.

-GTA Chinatown Wars (DS). This one actually sold well, but T2 wanted a lot more out of this, so they consider it a flop.
