Thanks in advance for your support.
Do you get results at all? Hard to check as that math font is a 
commercial one. If it's an otf font, I suppose it can be used directly 
as mainface math.


Libertinus is a free Math font and Minion Pro was available with older 
installations of the Adobe Reader.


To use the Minion font for math you have to create a new fallback for 
each set of characters because you need always a different argument for 
the offset key. To make everything a bit easier the fallbackfamily 
command provides preset list which already set he necessary values for 
range and offset.


% \definefallbackfamily [mainface] [math] [Minion Pro]
%   [range=lowercasenormal]

\definefallbackfamily [mainface] [math] [Minion Pro] 
[preset=math:lowercasenormal]


% \definefallbackfamily [mainface] [math] [Minion Pro]
%   [range=lowercasenormal,offset=lowercaseitalic,tf=style:italic]

\definefallbackfamily [mainface] [math] [Minion Pro]

% \definefallbackfamily [mainface] [math] [Minion Pro]
