Allow default settings to be filtered

Hi - would it be possible to add a filter so that the default settings for MarketPress can be influenced by other plugins, e.g.

--- marketpress.php.orig 2010-11-24 19:24:46.000000000 +0000
+++ marketpress.php 2011-01-06 07:37:26.497374001 +0000

);
- add_option('mp_settings', $default_settings);
+ add_option('mp_settings', apply_filters('mp_default_settings',$default_settings));
add_option('mp_version', $this->version);
