Yes.

Here's your error: if you do that, it's not the user who can change his
browser, but the system administrator. Those two are not always the
same.

However, there's a better way. From mailcap(5):

FILES
       $HOME/.mailcap:/etc/mailcap:/usr/share/etc/mailcap:/usr/local/etc/mail-
              cap -- default path for mailcap files.

In other words: you can create a ~/.mailcap, with the same syntax as
/etc/mailcap, and copy your preferred entries from /etc/mailcap there --
or create new ones.
