  The only model passed into the `guestEntries.beforeSave` event and returns from it is Craft's [EntryModel](https://craftcms.com/classreference/models/EntryModel), so even if you create your own `MyEntryModel` inside the event with it's own attributes and validation rules, there's not a clean way to return that model back to the controller to return to the template to display.
  
  The easiest thing to do would be to fork the plugin and change [GuestEntriesController](https://github.com/pixelandtonic/GuestEntries/blob/master/guestentries/controllers/GuestEntriesController.php#L175) so that's its using a custom `MyEntryModel` that extends Craft's `EntryModel` and adds it's additional attributes/validation rules as required.
