When used with a noun ために could have two meanings :

> (1) 学生のために、奨学金がある。
>
> There are scholarships _for (the sake of)_ students.
>
> (2) 学生のために、学校の規則に従わなければならない。
>
> Since s/he is a student s/he has to obey the rules set by her/his school.

With the second meaning, it is possible to express "the state of being a
student". Indeed, I can rephrase the second translation as "Since s/he is in
the state of being a student s/he" has to obey the rules set by her/his
school. Thus it is possible to express this state in the past.

> (3) 学生だったために、学校の規則に従わなければならなかった.
>
> Since s/he was (in the state of being) a student, she had to obey the rules
> set by her/his school.

In this sense of expressing a state, の is equivalent to である, right ?

So I can rephrase (2) as 学生であるために、... and since である and だ are somewhat
equivalent I should be able to rewrite this as 学生なために (since な is the 連体形 of
だ).

So the question is: Is all this possible or mere speculation ?

な, の, である and ために
Yes, all the reasoning above is just mere speculation. Now is the why (I'm not
sure to use the good terms so feel free to edit if you think it is necessary).

The major difference between だ and である is that である is a real verb (ie. it is
not defective) but だ is not. So there is no restriction in the use of the 連体形
of である but according to [助動詞_(国文法)
(wikipedia)](https://ja.wikipedia.org/wiki/%E5%8A%A9%E5%8B%95%E8%A9%9E_%28%E5%9B%BD%E6%96%87%E6%B3%95%29)
5th note below the fisrt chart there is this sentence the な-連体形 of だ is
limited to a few cases:

> 助詞「の」「ので」「のに」等が続く場合に使われる。連体形だが名詞を修飾することはできない。なお、形容動詞を品詞と認めない立場では別の考え方になる。

Which translate to ([thanks to
Choko](https://japanese.stackexchange.com/a/17934/4216)):

> Those 連体形 (=「そうな」「べきな」「な」 and 「です」) can be followed by particles
> 「の」「ので」「のに」etc...
>

>> 例: そうなの・べきなの・なの・ですの そうなので・べきなので・なので・ですので そうなのに・べきなのに・なのに・ですのに

>
> ... but cannot modify nouns (=cannot be followed by nouns).
>

>> 例: *そうな机・*べきな机・*な机・*です机

>
> By the way, those who don't recognize na-adjectives as a part of speech
> (=those who deny na-adjectives) think differently (eg. they consider きれいな机
> as "きれい + 助動詞「だ(な)」+ noun", not as "na-adjective + noun").

This explains why な could not be used in this case.
