Nah. English is an easy language, taught in a vast majority of high schools in Europe, the Northerners already all speak it perfectly, it has Latin roots and Germanic roots, it's fairly neutral, used by the US and Canada and is so far the de facto language of business. We should invest in English.
I've wanted English to be a mandatory second language after your native one in all of Europe for a while.
Also creating languages never works, see Esperanto and all those ridiculous lab-synthetized languages that pretend to solve all the problems and all end up showing the very same bias it was trying to avoid in the first place (Esperanto for example is WAY easier for a romance-family speaker than for say a dude from Poland).
If I were to design a new international language I would take the vocabulary and grammar from Basic English [1] and modernize the writting system to be fully phonetic.
Still, I'm afraid that such Newspeak-like language could be implemented only in some totalitarian dictatorship, so I hope that it won't happen any time soon...
We should better create an entirely new artificial official language so that nobody feels discriminated.
