MH3 is lacking a G-Rank because it's not a "G" game like MHP2g or MHG. No one complained that MH1 or MH2 lacked a G-rank.

And be realistic here, Capcom cannot have remodeled all the previous monsters from MH1 and MH2 and made all the armors/weapons into MH3 given their development time. It's not like that could have just thrown the psp files onto the wii. Also realize that over half of the content in MHFU is 3-5 years old.
