Possibility to use PhD Thesis work in another university
Since you're well published, idea coming to mind is PhD by publication.
Re-purpose as much as you can from your PhD thesis to publish in journals, collections, editions, etc. that would be of an acceptable by a global high-ranking university in your field, and that's the trick done.

Basically, it sounds like your original submission was failed, which is very unique and should reflect poorly on the higher-education institution that failed your submission.

PhD by publication would prove that your research is worth being considered, and you would only need to write an overall introductory paper that demonstrates the significance of your contribution to the field, and how the publications brought together contribute a consistent body of knowledge and expertise to the field.
