I currently using 2 trainers at once heh and it works, only function I miss in every trainer for this fantastic game is Infnite Components/Ores etc. etc. Since in the trainer I use only with drops/gathering if u get 1 it automatically goes to 100. But when u buy special items when u have some captured monsters. U only can have 1 or 2. So dunno if it's possible, but I would like to see that function heh.
