Lang where vowel length doesn't change vowel qualities (e/ɛ) (a/æ)?

It seems most langs that have both /e/ and /ɛ/, and/or both /a/ and /æ/, distinguish them as either short-long pairs or as allophones in free variation. I'm looking for one that would allow something like /e e: ɛ ɛ: a a: æ æ:/ as distinct phonemes that can be both short and long. Doesn't have to have all of the above mentioned. Just one with /e e: ɛ ɛ:/ would suffice. It seemed like Tiberian Hebrew fit the bill but nope, there's length distinction there.

Please forgive me if there was a way to find this on WALS. I tried but am an ignoramus.

ETA+ tl;r: are there languages that do not make lax vowels short and tense vowels long, but instead allow them as both long and short (not allophonically but phonemically)?
