Romanized:
Gi i halfamil ba sil an jan se am lin (now that i think of it, you should allow /l/ in the coda)
For Cyrillization, I think I will use my own system (to be more consistent with pronunciation).
Consonants the same as yours (except for /j/ which is more complicated and /w/ which is written with в), vowels:
а /a/ я /ja/
э /e/ е /je/
и /i/
о /o/ ё /jo/
у /u/ ю /ju/
Ги и халфамил ба сил ан ян сэ ам лин
For Arabicization, I'll modify the vowel system slightly.
/a/, /e/ and /i/ are the same, but /i/ and /u/ are written ـِـي and ـُـو (to distinguish from /e/ and /i/). If a syllable starts with a vowel, an alif (ا) is added before the vowel, with hamzah above for /a/, /o/, /u/ and hamzah below for /e/, /i/.
عِي إي هَلفَمِيل بَ سيل أَن يَن سِ أَم لِين
For Devanagarization, I will use the independent forms for zero onset along with the diacritic forms if the syllable has an onset.
गि इ हल्फ़मिल् ब सिल् अन् यन् से अम् लिन्
.. I have a lot of things to say about Graecization, I will use this system to be more... greek (spelling & pronunciation):
/m/: μ
/n/: ν
/ŋ/: γγ
/p/: π
/t/: τ
/k/: κ
/b/: μβ
/d/: νδ
/g/: γκ
/f/: φ
/s/: σ/ς
/h/: χ
/w/: β
/j/: /ja/, /je/, /ji/, /jo/, /ju/: για, γε, γι, γιο, γιυ
/l/: λ
/a/: α
/e/: ε
/i/: ι
/o/: ο
/u/: ου
So:
Γκι ι χαλφαμιλ μπα σιλ αν γιαν σε αμ λιν
For Koreanization, I realized that you used the same letter for /p/ and /f/, I will use ᄈ for /f/. Also, /j/ and /w/ are more complicated. Also, korean syllables cannot end in /t/, /s/, ᄈ so I add the 으 vowel to them.
기 이 할빠밀 바 실 안 얀 세 암 린
FINALLY
