I bought the alloy sump for our car after struggling to find a tin one that was sound. I got fed up with new pin holes appearing which I 'fixed' by drilling them out and inserting a 2BA screw and nut. Also they are difficult to seal having been overtightened and distorted over the years. I expect silicone gaskets have fixed that now.
The Alloy sump is very rigid and the crankcase isn't, so I think it helps in that department. We have the 'shallow' Allan Raeburn version rather than the deep 'Nippy' one. It doesn't hold a great deal more oil than the tin one. One day I may measure its capacity!
If the engine is being removed the sump will probably need to come off anyway.
I agree that the Seven engine is slow to warm up. This is remedied by fitting a thermostat. Our car is everyday transport all year round. In winter it would never warm up properly otherwise, even running with no fan belt.
