CV English is a concept that’s interesting but probably needs some tweaking. First of all, there’s no ending consonants, which is a pretty major error since English is, you know, not Japanese.
Second, there’s the issue of dipthongs and consonant glides. Unless you want choppiness then you should definitely find a way to include at least two-consonant glides.
Lastly, the format being CV doesn’t make too much sense. CV English reclists are essentially just Japanese with extra English phonemes, so if you want an ‘authentic’ English reclist it would have to be CVC at least.
Just pointing some things out! Have a great day :)
