I don't have the fonts, so I cannot describe the exact method. But see below and also have a look at Section 5 of
https://www.tug.org/TUGboat/tb30-2/tb95mahajan-cmath.pdf The description is old, and some of the file locations have changes, but the basic infrastructure is still the same.

Thank you for sharing this article. It seems that the
===================================================================
return {
    mathematics = {
        mapfiles = {
            "mtpro2.map",
        },
        virtuals = {
            ["mtpro06a-regular"] = {
...
===================================================================
codes may have done the job in the mathematics.make_font function.

In this snippet:
===================================================================
\definefontsynonym
  [LMMathRoman10-Regular]
  [LMMath10-Regular@lmroman10-math]
===================================================================
I know that LMMathRoman10-Regular will be used as the font synonym, @lmroman10-math is the
virtual font, but what does LMMath10-Regular stand for? I chose some random names in my typescript
but maybe there's some magic there?

The vectors mptpro2-mi etc are not defined. Look at math-ttv.lua for a list of predefined vectors (mapping type1 fonts to unicode symbols. It is quite likely that the mtpro fonts would follow the "standard" mappings; if not, you will need to create an approrpriate mapping for each font. This is not difficult (just monotonous).

I've already defined these vectors in the same .lfg file. What a tedious work it was, by the way. I thought
that would be irrelevant, so I skipped those codes. I'm sorry I didn't make that clear.

I almost forgot to mention. The font has its own \Relbar and \relbar characters rather than the equality
and the dash marks. What is the best way to use them? I currently put them in a private-use-area slot
in the vectors' definitions, but I'm not sure that's a good solution.

===================================================================
I guess the suffixes "f" "s" and "t" may correspond to "five" "seven" and "ten", but that's
not important. I could use one of them as the virtual font in the typescript:

Once this is done, rest of the typescript should work. It may be a good idea to try to see if you can get roman letters from mtpro.

If I claimed the font synonym with the virtual font directly:
===================================================================
# typescripts
\definefontsynonym [\s!MathRoman]     [MTPro10a-Regular@mtpro10a-regular]
===================================================================
the 10-size-version fonts were loaded without any problem. But if I want to use the designsize feature:
===================================================================
-- lfg
    designsizes = {
        ["MathTimeProA-Regular"] = {
            ["4pt"]  = "MTPro06a-Regular@mtpro06a-regular",
            ["5pt"]  = "MTPro06a-Regular@mtpro06a-regular",
            ["6pt"]  = "MTPro06a-Regular@mtpro06a-regular",
        ...
# typescripts
\definefontsynonym [\s!MathRoman]     [\v!file:mathtimeproa-regular]
===================================================================
the mathtimeproa-regular font could not be remapped to the correct virtual font with the appropriate size.
I just want to know how type-imp-ebgaramond.mkiv managed to remap the designsize filename
"file:ebgaramond-regular" to "file:EBGaramond12-Regular".
