Advanced Weapon Training + Weapon Familiarity

[Keraki]

I am building an Orc Rogue (Ruffian Racket) with a Fighter Dedication. I took Orc Weapon Familiarity to get access to the orc knuckle dagger for sneak attack. At level 12 (6th level feat) I saw the Advanced Weapon Training feat which lets me treat advanced weapons onf one group type as martial weapons. If I choose the axe group, the weapon training changes the orc necksplitter to a martial weapon. Will that synergize with the Weapon Familiarity to let me trea the necksplitter as a simple weapon?

Orc Weapon Familiarity was fixed to be in line with the other racial weapon familiarities.

It only affects your proficiency.

And IMO no. PF2 has little to no stacking of abilities, so you'd have two abilities that both make the weapon go from Advanced to Martial. That doesn't mean your GM can't step in, but frankly a 12th level feat (!) has far better options.
