Can i move to a G base flute from a C medium?

Its been around 4 months since I started practicing, I can play all three octaves, Play Pa to Pa' in one breath.
And my birthday is coming up so I wanted to get myself a bigger Bansuri.
I am not planning to get more than 2 bansuri unless needed, And I really like the sound of a G base bansuri.
Is it doable? I dont want to get something that I cannot even handle.
