Grounds can be on a shared buss. Neutrals must be on a separate buss.
Your idea is a very bad idea! Your output from the inverter should be in a separate sub-panel. Leave the 50 amp shore power as is. Second leg normally powers other systems such as water heater, washer/dryer, or second AC unit.
Enblethen, if line 1 and line 2 currently share a neutral bus, why must they be on separate neutral buses after the inverter is installed?
Why do you say splitting the existing panel is a bad idea? It basically creates two breaker panels within the one box. Jack Mayer describes the method here (scroll most of the way down to "Splitting" a 50-ampere Load Center): http://www.jackdanmayer.com/Wiring.html
