Plenty of languages use <e> for both /e/ and /ε/. Do these sounds contrast frequently in your language? Are there any predictable patterns to their appearance? (For instance, in most Romance languages, /ε/ is found only in stressed syllables.)
As for what diacritic would be best to distinguish them, that depends on the overall phonology of the language and what other diacritics are in use. For instance, doubling wouldn't be suitable if you contrast long and short vowels and an acute accent (<é>) could be confusing if you have phonemic stress, pitch, or tone.
