IMO this long/short vowel ambiguity is the #1 broken feature of English spelling, and could be reliably fixed by adopting an acute accent to mark long vowels (where a double letter isn't already doing the job).
As in:
I love to réad. Shé read all my books.
I watched the gáme líve. Shé lives at hóme.
Eurydicé had a fíníte supply of pátience.
Etc.
It wouldn't change any of the ASCII-only spelling rules, and would be a tremendous help to English learners. Since most text is written on smartphones nowadays, the new accented spellings would be immediately widely adopted as soon as the three OS vendors in the English world (Microsoft, Apple, Google) turned them on in their autocorrects.
Of course there's no instance or process that could push through a change like this because English, unlike French and German for example, is not a language whose evolution is actively managed by a national committee.
