Assuming the font is named "trump", you may try putting in the preamble 
of your LaTeX file stuff like:

\SetSymbolFont{operators}{normal}{\encodingdefault}{trump}{m}{n}
\SetSymbolFont{operators}{bold}  {\encodingdefault}{trump}{b}{n}
\SetMathAlphabet{\mathrm}{normal}{\encodingdefault}{trump}{m}{n}
\SetMathAlphabet{\mathbf}{normal}{\encodingdefault}{trump}{b}{n}
\SetMathAlphabet{\mathit}{normal}{\encodingdefault}{trump}{m}{it}
\SetMathAlphabet{\mathrm}{bold}  {\encodingdefault}{trump}{b}{n}
\SetMathAlphabet{\mathit}{bold}  {\encodingdefault}{trump}{b}{it}

The Greek letters, corresponding to the math alphabets letters or 
mathupright, should not be affected.

You'll have to rewrite the corresponding .fd file, for example 
/usr/local/teTeX/share/texmf.tetex/tex/latex/lucida/t1hls.fd, replacing 
stuff like

\DeclareLucidaFontShape{T1}{hls}{m}{n}{
hlsr8t
}{}

by

\DeclareLucidaFontShape{T1}{hls}{m}{n}{
s*[0.95] hlsr8t
}{}

but this might conflict with the [lucidascale], [nolucidascale] and 
[lucidasmallscale] options defined in 
/usr/local/teTeX/share/texmf.tetex/tex/latex/lucidabr/lucidabr.sty. 
Have you tried simply loading the [lucidasmallscale] option?
