I've had similar issues. With one client, the company font makes the report look so polished and beautiful and frankly more legible, that they've decided users will simply have to download the font to their computers for now. Because this report is huge and dense (~300 sheets and 15 dashboards, with each dashboard having waaaay more than the recommended number of objects on it) and everything is spaced to the pixel, maintaining two versions for different fonts is out of the question.
You could test whether switching the font globally will work in your case. I've found that because different fonts can vary so much in the amount of width or height the occupy that a straight switch-out often requires touch up formatting (text fields may need to be made bigger or the font a smaller point to fully show the switched-out font).
If you do maintain two sets of reports, could you put them both in the same workbook? This way, any data extracts or calculation changes will always apply to both. You could even set filters to apply to both the twin sheets. If you have to modify the structure of a view or dashboard, you'd have to alter both, but at least your data, calculations, and filters can be shared.
