I don't think it will be much of a problem, especially since
autovacuum will do only the tables that need it and not all the same
time.  But you can certainly try it.  Before changing the global
setting, try just changing it for one session with SET:

\timing
ANALYZE <some table>;
SET default_statistics_target = 100;
ANALYZE <same table>;
\q
