Depends on what you consider "fully melded" to be.

Given that the accessories and OH are the same in both sets, we can consider just the visible slots.

i180: 553 Craftsmanship, 524 Control, 12 CP

For i170, head, hands, legs, and feet can be capped using only Grade IV and lower materia (for 36 Craftsmanship, 328 Control, and 16 CP total from the four slots). CP on the main hand can be capped using a single CP IV (I don't know if that's the most efficient way to meld, but let's assume we do that for simplicity), and the body cannot have additional CP melded.

Assuming infinite gil and endless materia supplies...

Grade V, Control > Craftsmanship: 568 (+15) Craftsmanship, 572 (+48) Control, 24 (+12) CP
Grade V, Craftsmanship > Control: 602 (+49) Craftsmanship, 546 (+22) Control, 24 (+12) CP

No Grade V, Control > Craftsmanship: 536 (-17) Craftsmanship, 567 (+43) Control, 24 (+12) CP
No Grade V, Craftsmanship > Control: 578 (+25) Craftsmanship, 539 (+15) Control, 24 (+12) CP
