For small arrays like this maybe we should have a new array type that

Would it, in theory, be possible to have an "unpacked" array type? That
is, could we have constructors for which the length of the closure is
determined dynamically at runtime?
Certainly, but the amount of effort to implement depends on what you
want to support. e.g. do you want to support {-# UNPACK #-} on primitive
array types in a constructor field? That's probably quite hard. I
believe Duncan Coutts has been thinking along similar lines, we talked
about it once.
Or were you thinking of something more restricted?
Cheers,
