I know a pair of brothers named James and Timothy and Jimothy is of course their collective name. Always has been. How could it not be?Also Jimmy and Timmy.
A friend once took a sharpie to a buddy's name tag at work, changing Craig to Graig. At first he couldn't figure out why the customers kept calling him Greg, then some lady said something like "I've never seen such a unique spelling of the name Graig before. He looked down n saw his name tag. Hilarity ensued. 10/10 would recommend to anyone who works with a Craig at a job that people wear name tags for.
I have used Jessandra/Jessessandra, Jessinald, Jesstancia, Jessentina, Jessanca, Jesstoria, Jessody, Jesselia, Jessolet, Jessilda, Jessephine, Jessevieve, Jessentine, Jesselaide, Jessalie, Jesselope, Jessatrice, Jesselia, and many more. Just because she introduced herself saying her name was easier to remember than the other two that had just introduced themselves. Admittedly I can't remember their names.
You could always throw on a hyphenated middle name. She's no longer Jessica, she's Jessica-Anne.
I have a short full name, think something along the lines of "Sam Dal" (it's not, but same vibes), a lot of people ask what Sam is short for, but the answer is nothing, my legal name is just Sam. My friends will call me "Samuel Jay Dalford" as running joke. Made additionally funny because it's a masculine name and I'm not a man.
