Accept Insertion and reject deletion openxml - openxml

Question

I need to compare two Word files and merge all insertions into a third one.
I have managed to do that with OpenXML-Power-Tools and WmlCompare, but how do I reject only deletions?
Accepting insertions is easy with OpenXmlPowerTools.RevisionAccepter but I can't get the rejection of deletions to work, that way I would get merged file without revisions.
Should I take this approach or would you suggest different approach?
Rules are:
1) Text can be added anywhere in the file.
2) Text is always added to file, never deleted.
3) Files have a .docx file extension

It is relatively easy to reject, or undo, deletions. So, say you have the following sample paragraph with one w:del element that wraps a deleted w:r element.
<w:p>
<w:r>
<w:t xml:space="preserve">This is </w:t>
</w:r>
<w:del w:id="0" w:author="Thomas Barnekow" w:date="2020-02-16T14:37:00Z">
<w:r>
<w:delText xml:space="preserve">deleted </w:delText>
</w:r>
</w:del>
<w:r>
<w:t>text.</w:t>
</w:r>
</w:p>
To reject the deletion, you need to unwrap the deleted w:r and turn the w:delText into a w:t again. Without any further processing (see below), the result of your rejecting the deletion would look like this:
<w:p>
<w:r>
<w:t xml:space="preserve">This is </w:t>
</w:r>
<w:r>
<w:t xml:space="preserve">deleted </w:delText>
</w:r>
<w:r>
<w:t>text.</w:t>
</w:r>
</w:p>
As an optional step, using the MarkupSimplifier of the Open XML PowerTools, you could also coalesce adjacent runs having identical formatting, which would result in the following markup:
<w:p>
<w:r>
<w:t>This is deleted text.</w:t>
</w:r>
</w:p>
