For what it's worth I think it's a good idea. But choices will inevitably be very subjective and it depends what sort of threads you are interested in.
Some of the most fun ones involving creationists (in a head banging sort of way) involve Buzsaw on space-time physics and the Big Bang. Threads such as
The Unbended Curved Bar Space Slugout Thread or
Buzsaw Biblical Universe Origin Hypothesis vs Singularity Universe Origin Theory
If you want a more philosophical and nuanced type of thread then
I know God exists & the court of highest appeal is me. is a good one in my opinion (look out for Mod's contribution in that one).
Pseudoskepticism and logic and
Why "Immaterial Pink Unicorns" are not a logical argument are both debates I enjoyed and that whole topic of whether atheism is rational or pseudoskeptical is one that is still rumbling on into perpetuity........
Let me know what sort of topics you like and I'll try and think of some past good ones of that type.
