Best Interpretation: 過去を消して穴を埋めて作り変えよう。そうだそうしよう。


What is the best way to interpret this line from the song "Dark Blue Day" by
Straightener?

「過去を消して穴を埋めて作り変えよう そうだそうしよう」

I know: 過去を消して：Erase the past 穴を埋めて：Fill the hole

I'm not sure how to interpret 作り変えよう and そうだそうしよう.

Any help/insight anyone could give me would be most appreciated! Thank you. :)




作り変える means [to remake something, or to give it new
shape](http://eow.alc.co.jp/search?q=%E4%BD%9C%E3%82%8A%E5%A4%89%E3%81%88%E3%82%8B&ref=sa).
The idea here is to erase one's past and to reshape... oneself, I guess, as a
metaphor for living differently heading into the future. To reinvent oneself.

そうだそうしよう is just `そうだ。そうしよう。` connected into one group.

The others have offered some translations for the line but the general meaning
is about reinventing yourself while letting go of past mistakes.
