I think spending 5 Weeks to get a tool and a body piece that is already not the BiS is gonna hurt you in the long run, because what happens in 6 Months when you don't have the craft and control to do the 3 star? You can't meld anything to raise the caps so you are gonna need to start over from square one.

In the 3.0 Chimerical set you can already meet the crafting caps to craft the new 2 Star gear so there is no reason to spend red scrips on getting a Non Bis Tool and a Non Bis Body piece.
