I should live without an arranger for a while

You should. It'll do wonders for your playing (actually that's true, I'm sure Bill Lewis, Paul, and other pianist-types will back me up on that). Of course your approach to playing will be quite different. You may have to cut off your left hand, grow a new one, and start all over again

. I'm not saying give up the arranger (still the best instrument for solo gigging - when used with good taste), but it's kind of refreshing using that left hand to reach for keys instead of buttons, switches, and mod wheels - makes you feel more like a musician (JMO).
Good luck 'cause I know you're going to get something (the second your wife isn't looking

). We can feel the creeping gear lust all the way over here
