A question

I've spend the last few days trying to work out a Project question. I'd love to do something with biblical theology, but the things I've got in mind have been done before. I'd like to start with the Bible - I don't get excited at the prospect of comparing two theologians. Any suggestions would be gratefully heard, though there's every chance they won't be taken up as I'm very fussy ;-) Now there's a challenge for someone. Oh, and it has to be fairly contained as I've only got 8000 words to play with. Anyhow, here are my two areas of interest:

1. A biblical theology of the relationship between city and nature - including Isaiah 65:17-25 and climaxing in the vision of the New Jerusalem and the New Eden/Land/Paradise in Revelation 21 and 22.
2. A biblical theology of feasting and abundant produce (including numerous Old Testament references to wine and oil, milk and honey, which reach their zenith in Isaiah 25: 6-9) - and also looking at marriage - and at how the marriage feast in heaven (Revelation 19:6-9) will eclipse all earthly blessing and marriage.
