The elisp printer isn't really geared towards printing deeply nested values since it uses recursion. Perhaps you could just print the contents of your skip list as a flat list or vector for serialization purposes, and rebuild the structure when loading it back in again.

You could of course always write your own (non-recursive) printer, but be prepared that you may need to write a reader as well.

(I'd use a balanced tree-like structure instead of a skip list. Performance is similar, and allows for immutability and persistence.)
