yeah, go for it!
Art Of The Mask
In the presence of others conceal certain traits and replace them with atypical or normal ones to avoid being recognised as odd or unusual. This can involve changing things such as tone of voice, facial expressions, eye contact, speech patterns, and body language. Make these changes to match the dominant social norm of the group or environment you are currently in.
Masking and camouflaging can cause immense stress, as they’re different to the adjustments usually made in response to social cues. While most will moderate behaviour to enhance social success, masking and camouflaging differ as they are used to avoid negative consequences.
Art Of The Mask changes a deception or persuasion check into a performance check with advantage. Afterwards, roll d20 to determine what condition you gain from this list:
1 - 10 ● One level of exhaustion
11 - 13 ● Charmed
14 - 16 ● Stunned
17 - 19 ● Incapacitated
20 ● Frightened
Masking and camouflaging may protect from negative consequences in an encounter or social interaction, including violence. The consequences of failure can be enormous. If Art Of The Mask creates suspicion the risks vary from being thrown out, unwanted treatment, and even violence.
Recovery takes a short or long rest as long as you are doing nothing else during that rest, for example swapping spells or using a class or racial trait.
Whatever traits you have adopted become a permanent part of your mental inventory. You may enact a previous mask in inconsequential circumstances without after-effects, so long as you are in familiar company with no stakes on the table.

Oh i definitely wont be using it x-D feel free to take inspiration from it. It just doesn't feel right somehow, probably because I just edited someone else's text rather than make my own original. I don't have enough experience in mechanics or deep enough understanding of autism yet to wrote my own original autistic camoflage feat. It doesn't even really sound right to my mind, don't know how exactly. For real though if something went "a-ha" feel free to use it, I'm on the start of my autistic journey and don't yet know 5e mechanics like a DM. You definitely have a grasp on writing these sorts of feats with a certainty and understanding I don't have right now and I want everyone to enjoy a well constructed feat. How you wrote something from nothing i just don't understand... I can only do that with my character blurb.
