Somehow related (but not exactly) to Is it OK to translate and repost Stack Overflow questions/answers in different language?

Let's suppose I have a question in the following manner:

How do to x with y

Now, let's say a user is proficient with more than one language, in the current case, English and Portuguese (as of the time of writing, they are the public SO). Would it be wrong to crosspost on both SO and wait for anyone to answer?

Note that this is different than the linked question in the following way: we aren't purposely flooding a new SO with already asked questions by translation. Rather, we're allowing for good-written answers to appear, in different languages, at a natural pace.
