I was wondering if it's possible to do the following:

Let's say I buy a Korg PA900 (or any other arranger, for that matter) and I use it for its styles, but replace some of the Korg's sounds by the ones in my Motif XF's. For example, I choose a style, let's say Bossa Nova, but instead of having the guitar sound and bass sounds from the Korg play, I switch them with those of the Motif's?

Do you think it would work?
