With your setup and the fact that you don't spend the day in party cove, any decent pair of combo deep cycle/start batteries will work just fine.
If your setup works fine then I wouldn't worry about it and I'd leave the Perko switch pulling/ charging both batteries.
To run one dedicated for house one for start, isolate those loads to each battery directly preferably with some distribution blocks. At this point, the + to the starter will charge only the battery it's hooked to. Then link the 2 batteries with an ACR auto charging relay and the alt will charge both with the engine running but isolate them once the voltage supply drops below charging volts, 14+V.
This setup has worked well for me and its totally hands off. No switching required.
I installed a shore power charger as well though just to keep the batteries fully charged and maintained but it worked fine without it the first year.
