Disseminating math results in an interdisciplinary journal I'm a mathematician with physics background.  We recently obtained some results that, in my opinion, has interesting physics interpretations and thus deserve an interdisciplinary attention.

We already wrote a manuscript meant for a math journal.  It is super technical and not friendly at all to general audience.  I find that a pity, and want to write a kind of "short communication" (actually not sure about the format), in which I would avoid all the mathematical reasonings and only present the interesting interpretations that are relevant for material scientists and soft matter physicists.  The purpose is to disseminate our result to a more general audience, and invite interdisciplinary collaborations.

I have no experience of such manuscript.  My colleagues suggest that I should try top journals Nature or Science.  But I have the concern that such a manuscript has no "original result", which seems to be required by these top journals.  Then my colleagues argue that "interpretations" are original results.  But I fear that most of my "interpretations" are just personal opinions and won't count as solid result.

By the way, I do see people publish "long version" then "accompanied short version", which sometimes raises the concern of dual publication.  My planned "communication" won't be a short version, but a completely different paper with no overlap.

My question:  What should I do in this situation?  What journals welcome such manuscript (Nature and Science seems very unfriendly towards mathematics)?  How do people usually disseminate technical results?
There are journals in physics that encourage interdisciplinary work and also mathematical physics journals.  I have seen (and written) Physical Review Letters that have many pages of mathematics in a supplement.  See, for example:

Colbrook, Matthew J., Bogdan Roman, and Anders C. Hansen. "How to compute spectra with error control." Physical review letters 122.25 (2019): 250201.

You might do well adding an introduction that addresses the physics and then sending to a mathematical physics journal.

Do not be afraid of covering the same material twice, however.  Perhaps you write the paper as a math paper, and then a separate paper that covers in different words the same material from a physics viewpoint.  You can always call it a review or guide if that makes you feel more honest.  I recently employed that strategy and I hope Referee B feels this is alright.
