yes, definitely not a good idea!
The point about them is that there's a public well defined set.

We know that \keyword{} is a bit of a misnomer (inherited from
S's .KW) and denotes rather something like "category" (which has
to be relatively broad and still relatively well defined).
Consequently we have begun to use \concept{.} for `free' keywords
or key phrases.  Note that \concept{} entries will also be found
by help.search().

Adding new keywords to the KEYWORDS.db (and KEYWORDS) is
a possibility, but not to be done lightly.
We (R-core) have added a few new keywords in the past, but not
more than one or two per year (examples from the last three
years are  'graphs', 'survey', 'databases', 'datagen', 'internal').

We don't have a specific keyword for the realm of financial
mathematics and statistics (there's "ts" for time series and
"chron" for 'date and times'). 
I don't think there should be more than one though. Some cheap 
ideas would be one of
\keyword{financial}
\keyword{finance}
\keyword{finmetrics}
What does Insightful use for (their add-on module) "S+Finmetrics"?
