SD to CF adapter supporting 2 SD cards?

I have been looking at adapters to convert sdhc (sd cards) to cf (compact flash). I have only found adapters supporting 1 sd card, is their any that can support 2 sd cards?

example of single sd adapter

I have an Idea for the ipod mini flash mod hoping to make a 64gb flashed based (using to 32gb sd cards and a converter)
