which spelling is least likely to be mispronounced? (+suggestions???)

i’m nonbinary and i’ve given up on finding a regular name so i go by the letter A. only problem is i don’t want to go by an initial, i want it to seem like an actual name. i’ve only come up with Ay and Aye, first one i feel like would be pronounced more correctly but the second one i like the look of better. so if you could tell me which spelling has the more intuitive pronunciation or even suggest other ways to spell it (i have a feeling there isn’t😭😭) then please tell me! thank you.
