An alternative is to simply own your own english. Stop calling them grammar mistakes and start calling it grammatical diversity; there is no correct way to speak english. Every culture has their own unique way of learning english and each of them is worth sharing.
I bet that if a native english speaker wanted to mimic the grammar and intonation of your country’s english speakers, either to blend in or have smoother local communication, they’ll have a much harder time relearning english.
