Well, you could try just muting the instrument parts and go with B&D, or play as much as you can and put in what parts you need........ Some of the newer arrangers allow you to put in 'markers' to allow you to re-arrange an SMF just like you were playing a Style,,,,,,,,,

For me, the biggest advantage of SMFs is that I can use my left hand for the bender for solos, close to impossible if you've GOT to trigger the chords, plus it allows me to take the odd trombone solo.......... try doing THAT in arranger mode.

Don't get me wrong, arranger mode (or LH bass and arranger drums) are all useful modes for many songs, but don't get too tied to any one mode, they ALL have their uses.......... You wouldn't go round a golf course with just a 3-iron, would you? Everybody needs a putter and a little wood from time to time ;-)
