That is correct. In Japanese syllable clusters, 5 and 7 are the key numbers. What one says normally not only tends to sound better but also gets retained longer in others' minds if said with more phrases consisting of 5 and 7 syllables.than others. The best example may be seen in the syllable distributions in Haiku (5-7-5) and Tanka (5-7-5-7-7), but more importantly, the same tendency is seen in our everyday conversations and writings. Poetry and song lyrics are no exceptions.

Also, I thought 空も飛べる was a more dramatic & emphatic version of 空を飛べる, but now it's uncertain to me, since I'm thinking that it can be は, not を, plus there's a possibility that it's linked to the phrase 不思議なまでのゼロの空間. Can you help me understand this point?

In the phrase 空も飛べる , it is not the 空 that is the subject for the verb. The subject is the hidden "one" or "you". You are correct in thinking that 空も飛べる is a more dramatic form of 空を飛べる. 空も飛べる is the same thing as 空さえ（も）飛べる.

The reasons that I say 空も飛べるよ belongs with the two preceding lines rather than what follows are:

1. It ends with the sentence-ending particle よ.
2. The next phrase starts with そんな, which would suggest that something has been stated and a new statement is being made by saying そんな = "that kind of ~~ is ~~."

Now this is interesting. Would you mind explaining more about this? I just can't figure out how it modifies the verb.

Ah舌を出して笑う　空虚なる支配は
転移を繰り返し　浸食をする
叫ぶような熱さえ　僕はただ逃げ込む

I am reading this part as follows:

Ah舌を出して笑う空虚なる支配は、
転移を繰り返し, 叫ぶような熱さえ浸食をする。
僕はただ逃げ込む。

叫ぶような熱さえ may not "modify" 浸食をする in the English sense of "modify". Yet in Japanese, we do say that first part 修飾する the second part. This 熱 is being "浸食する'ed = eroded"

This may not be a best explanation but I hope you can follow what I am trying to say.

Ah, so the が in 愚かなる願いが is "but", not the subject marker, isn't it?

No. It is a subject marker. 背きたい道順&愚かなる願い is the subject.

Um, does 常識を離反した modify 拒絶 or カオス?

It modifies カオス. Both 常識を離反した and 拒絶さえ許されない modify カオス.
