Importing data from wp-types: is it possible?

I always used wp-types (well, since is out-there) and found myself quite comfortable with it.

But today I'd like to give a try to CustomPress, as it looks very interesting and with more features than wp-types.

But I don't want to mess my database and I'd like to know if there is a way to import all my custom post types, taxonomies and custom fields from wp-types to CustomPress.

To me it's either ok the hard way (sql scripts) or an existing feature.
WP-Types has an export/import feature for custom (is simply a quite readable xml file: I can provide an example, if needed): perhaps CustomPress could read it and do the job for me?
