index idea for system catalogs

For the unique system indexes, does it make sense to do a hash index
instead of the B-tree?

Also, does it make sense to implement a bitmap index (like Oracle 8i)?
That would work for even non-unique catalogs, although doing it
"right" would be a lot of work.

Is there interest in me looking at doing bitmap indexes (assuming
someone isn't already working on it)?
