Well, you can try to copy the existing test, but you won't know how to calibrate any of the scores. It's a reaction test, based on times. The most you can copy is "see a letter, press a spacebar" functionality. They're not going to give you the source and they're not going to give you the base data. You can test people for times but you don't know the cutoffs or the norms for those times. You don't even know if high or low of a norm is a sign of attention or inattention. You'd have an easier time replicating the MMPI. But go for it.
