Batman and Flash Gordon

I think that Batman and Flash Gordon would be an interesting team up to see in the comics because of their mutual roots in the old black and white cliffhanger movie serials.  Despite their quite obvious lack of big budgets, I have always found those serials to be quite charming and some of the stunt work and plot twists are pretty effective.  What would have been really cool is a serial from those days combining these two action stars in one epic adventure!
