Oh I'm sure there's some 9th-level Druid spells you can do.
Heck, if you like lower level spells so much, take Heighten Spell and make those favorite 5th and 6th level spells also 8th and 9th level spells, better save DC.
Here's a list I have from my official WotC 3rd Edition spell list file for 9th level Druid spells.
