One option is that what you're describing just isn't possible, that humans are already butting up against some kind of limit which is not avoidable simply by being raised with a different language.

Another option is that one can be raised to think in "pre-compressed" structures, but nobody does because it's a bad tradeoff, dropping "general thinking" performance with a worse impact than any "faster speaking" benefits. (Such as being simply slower, or more error-prone, or more demanding on attentional resources, etc.)
