I have two identical systems except that on in south facing and one is split EW (2mppts). I can compare the two systems directly and on sunny days the south facing one peaks at around 50% more power in the middle of the day, and the EW one just beats the S first thing and last thing, but the power then is very low anyway.So yes I would say you can increase the number of panels on an EW system compared to what you would have on a S system. Provided it's total inverter power you are worried about (although in any case inverters just top out when presented with more potential power than they can handle, and most allow for 50% more PV power than the inverter can handle)However you would need to check maximum voltages on the strings. You could get full power and voltage on one string at some point during morning or afternoon in summer.
