Or just drop very? Those are all good descriptive words by themselves, and the alternatives aren't really guaranteed to not need modification with something like very.
Apart from that, there's honestly a lot that bugs me about it. For the most part though, these are all depending on the use case and would require you to have a relative mastery of english.
A couple are...
Simple and basic can generally be interchanged with each other. There are also times when very simple means something completely different from basic. (eg. chemistry)
As someone mentioned, "very perfect" wouldn't really be used in the implied sense. It would be more used to convey extreme fragility, in that destruction happens with the slightest problem.
Another one is that you can be very open about your thoughts/feelings, but you wouldn't necessarily announce them by being transparent.
