yo YM;what did you do as far as to get here from stock? It sounds good,I'm not sure how to A/B it with the stock sound.
imo;it might be a mistake to leave #9-the 1' out.Most jazz/gospel cats use that(1');the # 5,7,8 aren't all that useful.
there's a cat on u-tube who programmed his XS with B4 sounds-so he had all 9 bars.Since you only have 4 to work with;it might sound better to develop your IdeA a bit!
Maybe combinations (like you did with # 1 being 1 st 4 bars) to get variations.If I were to do something like this,it would be more useable to have the first 3 faders same as 1 st 3 bars;allow 888,858,688 settings ;and the use the LAst bar,for #9,or combinations like you tried.That would give you (hopefully) a little more realism.
I have my CX3 Korg mounted under my XS 6;the Motif sounds are almost as good as a dedicated clone! The xs just sounds a little thinner;probably due to memory considerations.hope this is helpful feedback!
