Sounds reasonable.

I'd make the function private: org--property-get-separator. It is not
intended as an API function.

Please quote the function name as `org-property-get-separator'.

Please, use double space "  " to separate sentences. Also, see

This example is a bit confusing because it is unclear what you want to
achieve and why you also need to set inheritance.

This defcustom type does not match what you described in the docstring.
You need something like :type '(alist :key-type (choice string (repeat string)) 
:value-type string)
