Quite possible. Lucida doesn't provide all the ec glyphs anyway (č is
not present), but the virtual font on CTAN apparently fakes it
successfully by placing caron over c and taking two glyphs
(successfully only in technical meaning, so that it works in the first
place; typographically it's obvious that the one who did the virtual
font has never used that glyph).

The metrics are there already, it's only that their naming scheme is
weird. But unless someone really depends on raw tfm names, the
following should work OK:
\starttypescript [mono] [lucida] [ec,texnansi,8r]
\definefontsynonym [\typescriptthree-lbtr]
[hlcrt\typescriptprefix{e:\typescriptthree}]
[encoding=\typescriptthree] % LucidaTypewriter
\definefontsynonym [\typescriptthree-lbtb]
[hlcbt\typescriptprefix{e:\typescriptthree}]
[encoding=\typescriptthree] % LucidaTypewriterBold
\definefontsynonym [\typescriptthree-lbto]
[hlcrot\typescriptprefix{e:\typescriptthree}]
[encoding=\typescriptthree] % LucidaTypewriterOblique
\definefontsynonym [\typescriptthree-lbtbo]
[hlcbot\typescriptprefix{e:\typescriptthree}]
[encoding=\typescriptthree] % LucidaTypewriterBoldOblique
\definefontsynonym [LucidaTypewriter]
[\typescriptthree-lbtr] [encoding=\typescriptthree]
\definefontsynonym [LucidaTypewriterBold]
[\typescriptthree-lbtb] [encoding=\typescriptthree]
\definefontsynonym [LucidaTypewriterOblique]
[\typescriptthree-lbto] [encoding=\typescriptthree]
\definefontsynonym [LucidaTypewriterBoldOblique]
[\typescriptthree-lbtbo] [encoding=\typescriptthree]
\loadmapfile[lucida.map]
\stoptypescript
If one doesn't need the texnansi-lbr synonyms, it can be done more
efficiently in a single step.
Alternatively we can of course ship the metrics, but assume some LaTeX
user with an already working LaTeX installation of Lucida - wouldn't
it be great if it worked in ConTeX out-of-the-box?

Do you mean some other math fonts? The package on CTAN has the
following tfm files (and maybe some extra ones in vf that I didn't
manage to check completely yet):
hlcda LucidaNewMath-Arrows-Demi <lbmad.pfb
hlcdim LucidaNewMath-DemiItalic <lbmdi.pfb
hlcdima LucidaNewMath-AltDemiItalic <lbmdo.pfb
hlcdm LucidaNewMath-Demibold <lbmd.pfb
hlcdy LucidaNewMath-Symbol-Demi <lbmsd.pfb
hlcra LucidaNewMath-Arrows <lbma.pfb
hlcrim LucidaNewMath-Italic <lbmi.pfb
hlcrima LucidaNewMath-AltItalic <lbmo.pfb
hlcrm LucidaNewMath-Roman <lbmr.pfb
hlcrv LucidaNewMath-Extension <lbme.pfb
hlcry LucidaNewMath-Symbol <lbms.pfb

What does robust mean? One needs to buy the font anyway, so it won't
work out of the box, but it would be nice if it worked out of the box
with the files that TUG does ship. Metrics in TeX live don't really
help without pfb files and if one installs pfb files, one may easily
copy everything else along. Of course we can add the metrics to
minimals (optional install), but I would prefer them to match the ones
from TUG (currently they are also available on CTAN).

I can double-check which ones are not needed, but we could drop at
least the 8r encoding.

I'll take a look. I have noticed that math-vfu does use the metric
names from the latest set of fonts.
Hoewere one needs to keep in mind that it's not 100% compatible
encoding (the "rm" doesn't 100% correspond to the same glyphs in LM,
but it's rather a roman variant of "mi", so at least the brackets need
to be taken from somewhere else). Also, there are many extra glyphs
all over the place that should better be mapped to unicode if one
wants to use them.

For me it is the less files - the less problems. If some other files
are already considered "standard" and work out of the box, it would be
nice to use those. (Unless someone convinces Karl to ship a few extra
metrics, but you already said that he declined the idea.)

I will check that (one needs to check the vectors anyway).

But š and ž *are* part of font and part of texnansi encoding.

The virtual font *is* ok. It is MKIV that doesn't care about that virtual font.
In short:
- texnansi -> is tfm; all the glyphs are present in font
- ec -> is only vf; some glyphs are missing in font, but are composed in vf
Is there any way to get those composed glyphs out in mkiv?

- almost default -
It's quite ok for the first approximation, but still needs some fixes.
If nothing else it offers way more glyphs than CM/LM.
