Hi Damien,
I might misunderstand what you want, but you could play with this:
\definecharacterkerning
[FrenchRoman]
[factor=-0.1]
\definehighlight
[FrenchRoman]
[style=\setcharacterkerning[FrenchRoman]]
\startTEXpage[offset=1DK]
\dorecurse{20}{%
#1: \Romannumerals{#1} or \FrenchRoman{\Romannumerals{#1}}\par
}
\stopTEXpage
