Yea, ya will

Just consider the models I've shown you there.
The sealed, semi sealed cap as the tank water comes into the sump is the key.
The bag filters solve the mechical filtration issue the best way
Bioballs and/or a large sponge takes care of the biological side and you also will reduce both noise and evaporation by sealing the inflow to the sump.

If you want, you can add Purigen or activated caron or zeolite etc for chemical filtration in the sump.

You can add the CO2, the heater, the UV and have only the in/outlfows in the tank.

If you glue cork bark to the overflow/pipes in the tank and cover it with plants, you will not even see that.

My 90 gal from 15 years ago had that.
