Of course, if we can create a Latin based abugida with vowels as letters and consonants and diacritics, we can create a real abugida with Latin letters, too.
What’s an abugida? An alphabet where only the consonants have letters, vowels are added as diacritics. Like Brahmic scripts used in India and Southeastern Asia.
It’s not complicated to turn Latin script into an abugida. For first, let’s remove all letters A that follow a consonant and replace them with an acute accent. Now we h́ve to write A’s only when they are at the beginning of a word or after another vowel – in all other ćses, only the diacritic is written above the preceding consońnt. Then let’s do the śme with letters I and repĺce them with a dot. Now we ćn wṙte even shorter text. The ṡmpŀḟćṫon process ćn include ćses treated speċally, ŀke the sylĺble “li”, wṙtten ẇth a ṁddle dot. Now, the tḣrd v̇cṫm is O, subsṫtuted by a gŕve accent. (H̀w d̀ I ch̀ose the accents? Just by pers̀ńl ŀke.) Then we repĺce U’s ẇth a ċrĉmflex and the text sl̀wly t̂rns int̀ a ċpher c̀de, b̂t we ḋdn’t ḟṅsh yet. We als̀ ch́nge Y’s used in v̀wel r̀le t̀ ṫldes, onl̃ c̀ns̀ńnt ones ćn ŝrv̇ve, and th̀se used in ẁrds ŀke “ḿy” bećuse they f̀ll̀w aǹther v̀wel.
As ỳu ćn see, I left one v̀wel unt̀uched: E. Tḣs is the m̀st freq̂ent v̀wel in Engŀsh, and tḣs ab̂ġd́ is b́sed on Engŀsh. Acc̀rḋng t̀ the s̃stem of Bŕhṁc scṙpts, the m̀st freq̂ent v̀wel is unwṙtten and unḿrked. It’s incl̂ded ẇth all the c̀ns̀ńnts as an inherent v̀wel, theref̀re, a c̀ns̀ńnt ǹt weaṙng a v̀wel ḋacṙṫc is pr̀ǹunced ẇth the inherent v̀wel. S̀, in Bŕhṁc scṙpts, a letter K d̀esn’t mean ĵst “k”: it is pr̀ǹunced as “ka” or “ko”, depenḋng on the scṙpt. In our Engŀsh b́sed ab̂ġd́, it ẇll be pr̀ǹunced as “ke”. B̂t bef̀re we ćn intr̀d̂ce tḣs feat̂re, we m̂st add a ẃy t̀ rem̀ve the inherent v̀wel, f̀r ḟńl c̀ns̀ńnts and th̀se t́k̇ng ṕrt in a cl̂ster. In Bŕhṁc scṙpts, a speċal ḿrk serves for tḣs p̂rp̀se, the v̇ŕḿ. Our one is the underd̀t. S̀, a d̀ṭ uṇdṛ a c̀ṇs̀ńṇṭ maṇṣ ǹ v̀wḷ, ẉḣl ǹ ṣpċaḷ ḿṛḳ maṇṣ E.
