Extend index structures of HSQLDB

Do you think it is possible to extend the index structures of HSQLDB 2.0?

I've seen that HSQLDB implements AVL trees, but I'm not sure if I can extend that by e.g. implementing R-trees in the HSQLDB code. Are the index structures in HSQLDB even materialized?

It is possible to develop an R-tree implementation of index for HSQLDB. But to make use of such indexes additional query syntax is also required.

The index structures for CACHED tables (disk based tables) are persisted.
