Does this sound like a reasonable choice?
To select a bansuri you should think of two things:-
1. What kind of music do you want to play
2. What kind of tone do you prefer
The G bass is a medium sized flute. The advantage of that scale for you would be that it is the closest bansuri to the western silver flute and so the transition from a western flute wont be too difficult.
If you want to play classical/semi-classical Indian music then you should consider going for a longer bass flute like the E bass flute.
There is no fixed criteria and the matter is of personal choice.
