Neat topic, its got me stumped! Thanks for sharing!
I humbly offer a few perspectives.... apologies for a novel.
You can name your descendent any name you wish...
so long as that word or phrase is lawful, and is not trademarked/copyrighted.... (sometimes people aren't allowed to be addressed by their full name if it were say 'Plexiglas', or 'iPad/Apple' etc).
so, a substitution cypher (where you move all the letters left or right, and is all consonants for example) wouldn't be permissable.
Some historical figures (religious prophets, dictators etc) can't be used in a name.
I wouldn't want to name a person in such a way as to ostracize them:
maybe have a 'far out' name for one name, and a 'regular name' for the other.... that way, when the minor comes of age, they can choose what they'd like to be called, they can retain their eccentric name if they want, or they can change their name via Deeds Poll.
Try to refrain from names with lots of plosives (7 or more syllables, all being plosives),
onomatopoeia or which are extremely difficult to pronounce, as plosives sound aggressive and harsh in many languages, and pronunciation issues can be offputting (some theories suggest a causal link between name frequency and name complexity in professions as a lack of progress).
A weird one I had to have the person filling out the form complete,
was a female named 'Ker-A'
(to be phonetically pronounced - ker-dash-ah).
They were so embarrassed, and my partner gave them a hard time till they examined 'Ker-A's driver's permit - it was on their drivers permit and insurance details.
I reminded my partner that hey -
Superman also had the birth name 'Kal-L', and he's the world's greatest hero (duh), maybe their parents really liked superman?
Was it a cool name? yeah... but was it worth the embarrassment at paperwork or official time?...
So, Homer Simpson had a middlename, Jay. It was pretty average.
Colors - Red from "That 70's Show", Violet (Willy Wonka and the Chocolate Factory).
Doctor Who doesn't have a name (though I suspect it is Faustus, as in the Faust Myth).
Costanza came up with food-based names, like Soda, or Cola...
So, for example, a palindromic name "Hannah" etc... they're fun!
Seven of 9, Tertiary Adjunct of Unimatrix Zero-One, had a number/fraction as a name. Somehow... sqrt -1 doesn't have quite the same ring to it...
I feel that Hungarian names are cool - they're huge, as they take from the mother and the father, similar to Spanish names etc...
if you could make a name that uses all the characters of the alphabet, that'd help the kid in schoolgames where they have to play anagrams...
So, having a couple of names would be neat. You can have as many as you want, in theory...
maybe try some portmanteaus from 2 or more words?
For a female:
Pan (short for Panacea),
Cassandra (the ancient greek goddess cursed with 100% accurate vision of the future, but without the ability to change her fate),
Xiphoria (a portmanteau of Xion and Euphoria)
Oxymora (the plural form of oxymoron),
Eudaimonia (the pursuit of happiness).
Anagnorisis (short form, Ana. For the moment of profound realisation).
Qaenne (Cain/Kane in feminine, Kay-enne)
For a male:
Zugzwang (Z for short, pronounced Tsook-Tsvaung, like wolfgang... a German Chess term, for the disadvantage cause by the compulsion to move).
Yrimir
Garan (uncommon alternative to Gavin).
Zefram - the name of the fictional character who invented Warp Drive in Roddenbury's Eutopia.
Zimyre (pronounced Zim-eer, an uncommon Greek/Turkish name).
Alec (for obi-wan's actor),
Phalynx/Phalanx - aside from the potential mockery, Phalanx is also a military term.
Draycyn (mutation of 'Jason').
Pyros/ (represented by the symbol for Pi, is an alternate spelling. Means 'Shiny Rock')
Porphyry (after the philosopher) or Carl (after Sagan).
Phlupzidian --- an eccentric acquaintance change his name from Philip to this when he changed gender alignment, it looked cool on a passport.
Igneous/Ignatious (similar to peter, though this name can be mocked),
Etcetera (represented by an Ampersand, I have seen this as a name from a particular faith background...).
Erstwhile/Erstwhyle
Baeo (as in, beowulf).
Quintillion, (a big number)
Quorum (an argument, Q for short...)
Qaen (Cain/Kane)
