Yes, that is something I can agree with. But it will take 3-5 years. 
 
Making LDC a default compiler looks like a more rational
solution. By default, I mean a branch where we do the main work
on the compiler and DRuntime and what is used to make the first
release of the new version of the compiler.

No, I do not see any benefit from this. 
 
I just realized why we still have DMD as the default compiler and
why probably we would have it in the near future.

D Foundation wants to have full power to make all key decisions.
Making LDC a default compiler would also mean they would need to
share their authority with others. That is only my opinion, I
don't pretend it is right.

If D  Foundation would selected LDC as a default compiler I believe LDC would need to accept D Foundation as their leadership
