Not meaning to piggyback but would this theoretically be the most optimal for MB minus insanely rare gear like HQ Amalric or would there be a more optimal setup? Helios feet is MB +10%.

With Lathi, this set has 194 INT, 284 MAB, 102 M. Acc vs your 182 INT, 294 MAB, 88 M. Acc.
This is assuming perfect augments on all Hagondes and all Helios. Helios is a lot more reasonable to get 20 MAB/20 Macc on than for Hagondes to Reach >25 MAB, so adjusting for that, it's more like 284 MAB vs 284 MAB. Even if Helios wasn't to have 20 MAB/Macc, 17 is still common so it's still 278 vs 284 MAB, and the INT will make up the difference in lost MAB.
Now, taking into consideration M. Acc differences between the 2 sets, not to mention that you can give up 10 MAB for an additionall 30 M. Acc, it's easy to see why using NQ amalric wins quite easily. Your set also requires a 10 MB dmg Helios Boots whereas my set only requires 15 between the head and feet.
If we take into account Lyramion's suggestions, your set becomes 294 MAB, 107 M. Acc, 186 INT, which is certainly a lot closer. I would say either set works about equally well and go with whichever you have easier access to, assuming you can easily get a hold of 10 MB dmg helios head/feet.
