Without any more context, the snippet in your OP "feels like" it is really four beats in a bar, with the left hand playing triplets. But almost everything in your notation contradicts that visually. The main purpose of music notation is communication, and this disconnect seems (to me at least) to be a major communication failure.
If you really intend this to be a complicated cross-rhythm, then your notation is fine - though adding a few accents might make it clearer.
But if you actually mean "four beats in the bar", then write it that way.
I don't really see how splitting each bar into four and using longer note values would make it any clearer. 32nd-notes and/or triplets won't "frighten the horses," so long as they communicate what you really mean.
