\installfont doesn't apply metric files to each other, it just reads them
in sequence, pretty much as if there was one file which just \inputmtx'ed
them all in sequence.
What you should do is to have a second \reglyphfont applied to your kerns
file. There is no requirement that there has to be glyph definitions in
files \reglyphfont is applied to, it can be just as well be only kerns.
\reglyphfont can also be used to filter out data from this file, if there
is anything there that you don't want.
