The idea is great, but the site itself isn't so ready for this - Import has several issues:
1. The hierarchy after import is totally broken, the folders are mixed.
2. There is no support for non-latin titles in folders and bookmarks.
3. If the imported html file contains not appropriate bookmark (e.g. that points to internal files), the entire import fails. I understand, that it is impossible to save such links in cloud, but it shouldn't cause to fail the import itself.
