Can Alter Self give you hands on extra limbs?

Question

Can the Change Appearance option of alter self be used to give a four-armed creature hands on those other arms?

You transform your appearance...You can make yourself appear as a member of another race, though none of your statistics change... your basic shape stays the same

In particular I was considering the Simic Hybrid race from Ravnica which can have additional appendages, but not additional hands:

You have two special appendages growing alongside with your arms. Choose whether they're both claws or tentacles.

Can alter self change these appendages into functional arms with hands, say by emulating a girallon (a four-armed ape)?

Answer 1

No, you functionally cannot

You can make yourself appear as a member of another race, though none of your statistics change...

A creature's game statistics include everything that is on the creature's stat block or character sheet, including its actions. If you had additional hands that were functional, they would enable additional actions, and alter your game statistics.

You however can make it look like you had additional hands on these extra arms, as long as your original body has extra appendages that you could disguise as arms.
