You can use a site like SoundCloud Playlist Downloader if you're looking to get all of your podcasts from one playlist downloaded.
As far as an RSS feed in Pocket Casts, it definitely is possible according to this guy's website. It looks like he took an RSS feed URL from his user profile.

You would have to search using one of the aliases/entities for 'heavy greek cross'.
See here: http://graphemica.com/%E2%9C%9A
For Sound Cloud, use the URL escape code:
%E2%9C%9A
Example: https://soundcloud.com/search?q=%E2%9C%9A
If you type into the search box, Sound Cloud will add '25'.
Example:
q=%25E2%259C%259A
So you must remove the '25''s from the URL.
