Why?
We're talking about a licence agreement between (say) you and me, where we have agreed to licence our content to one another on terms set out in the OGL. So we've promised one another to publish, under the specified conditions, text that is copyright WotC.
If we decide to instead use
@rcade's solution, we are in breach of our promises to one another but the breach seems pretty trivial, and (assuming we both want to preserve our particular OGC ecosystem) neither of us is going to complain and each of us could even make a statement that we waive our right to have the OGL published in full.
(There are complexities around section 13 - does our breach terminate all the licences if we don't cure? - but it should be possible to issue some sort of properly drafted waiver to avoid that result for this particular breach.)
However exactly we do it, I don't see how WotC has any interest in the matter.
