I’ve often played in similar small area supporting acoustic guitars. I find the sounds I needed are usually a bass and then (depending on the song selection) perhaps upper piano/strings/pad. I use a CK61 which has an Octave function available for each voice. The built in speakers are nice - maybe even good enough on their own in a very small space? Best part - it’s 12lbs and runs on batteries so easy to tote and set up and less cables.
But if you’re considering a Psrsx700 anyway - sure - that’d be a great option and could even add more possibilities!
