Sure it would be fine if the kids were relatively tiny, like under about 8, they would learn the language in no time.
With older kids it could be a disaster with no learning support.
On the other hand, at least they would learn a language (eventually)
Schools are teaching precious little anyway, I have two kids and the only one who is learning anything is the one who needs extra help.
The 'bright' one learns NOTHING apart from in language classes.
So maybe I will move to some country that would do them a favour linguistically.
One could always find a private home tutor for after school help for the first few months.
As for the mother's language problem, hey, she could always learn the language.
