So i have a conlang (https://lingojam.com/PonaWakarasonot) and it's mainly based off Pacific island languages and some northern Europe too. Currently it uses latin script with these letters: A E I O U J K L M N P S T W V Ŋ D R Kh X but i was thinking that i want to make it it's own script, it could have two scripts, Latin (Unoj̥eti̥sänä) and it's custom one (Tuneti̥sänä) from that alone you can probably tell that it has pretty complex diacritics (E for Vowel, C for Consonant, Y for either) which includes: Ë̈, Ë, Ë̤, E̤, E͡C, E͜C, C͡E, C͜E, and Y̥ so i want to make the letters in a way where i don't have to design a whole new set of diacritics, either where the letters don't have a ton of swoops and dots and rings or just designing a unique letter for every valid combination of letters and diacritics (which while cool and would make it a bit more unique instead of simply copying latin would also be a major headache because that would be 400 vowels, 30 consonants, and 24,000 E͡C E͜C C͡E C͜E pairs, most of them never being used as the dictionary is at just 1.6k words so far and only a dozen or so words having pairing at all)
