Can I use uninstall the ProFTPd service and use ProFTPd-mysql ?

[PlymWS]

I want Plesk 8.0.1 to use the ProFTPd-MySQL service rather than the standard ProFTPd program.

My reason is that I can then use the ProFTPd-MySQL Administrator to add multiple FTP user accounts to my domain rather than be limited to 2 (User and Anon).

Can I uninstall or disable the ProFTPd service and install the MySQL service ?
