Ideally I susppose - I'm dyslexic mainly affects my spelling - and my children seem similar.
It is suspring how many easier to spell languages did go through a spelling reform at some point.
I just don't think it a practicle suggestion as there's no overall control of English as a langaue - and it's very widespread.
I do think better teaching of spelling would massively help many who currently struggle.
I stepped in with structured programs at home at very young age with younger children and they have fewer spelling problems than eldest - though she was only Y2 when we started helping her but so many mistake had been fixed at that point and she wasn't being corrected in her school work with spelling though out primary.
Spelling tests don't teach spelling but seem to be expected to teach spelling and they don't really help struggling spellers get better though the do help fix idea that the child is bad at spelling.
