Bale was the best Batman ever, that said, putting this Batman on a Superman movie would make the Nola trilogy ridiculous. Every crisis Batman faced (Scarecrow - joker - Bane) would last 5 seconds in the hands of Superman, so, it will be a instant joke for every nerd and internet reviewer in the world. I hope Snider and Nolar are smart enough to realise that.
Also, such a goofy movie (Supeman and Batman together) would destroy Christian Bale carrier, and he is one of my favorite actors.
