word order - Usage of indefinite article and too

Is there any alternative to this construction?

It was too stupid a question.

I mean, can we somehow put the 'a' in a different position and is it used in English (maybe informal) or the version I've given is the only possible? Also, I feel as if something's wrong in my previous sentence, it would be very nice if anybody corrected it.

Answer

Your sentence,

It was too stupid a question.

is good and correct. However, you can rephrase it if you'd like,

I thought (that) the question was too stupid.
Let's forget the question -- It was too stupid.
NOT It was a too stupid question.
