To achieve what you'd like to do, you will need to use Data Templates as a data source. The data template can then reference the JDBC connection to the BI Server. Using data templates will allow you to solve both of your problems (non-flat result sets and linked queries).
Using Answers as a data source or using SQL against the BI Server will always result in a flat XML structure getting generated.
