I appreciate your comment as a genuine expression of confidence and hope. However, it seems that this generic comment could reference an existing initiative that is already being used by several office suites http://www.documentliberation.org/

So it's not like there aren't already chances for the integration you propose, that span a broader section of the FOSS landscape than just LO/AOO. But ... You'll see that Document Liberation is spearheaded by LO/TDF and ignored by AOO/ASF.
