My engine takes ~9 litres of oil in it's current wet sump configuration.
Is it a simple case of maintaining that volume when moving to a dry sump system, or is it desirable to add some oil volume (or conversely remove some)?

Existing volume is fine. Just fill sump once the dry sump is installed, using stock amount for the sump (unless you changed the volume of the sump) and run the engine to fill the rest of th system and do a final adjustment when you shut down to accommodate the slight added volume of the new components, hoses and pump.
The replacement for the existing sump will reduce the volume somewhat, it's a bit of an oddball engine being a flat six as it's got a scavenged sump in each head, then the central sump for the crank to which all oil is returned prior to being circulated again.
In essence it'll have three small scavenged sumps which return individually to the dry sump tank, which then supplies the current oil pickup point.
Two big perks of a dry sump (other than cost) is that it'll handles leaks (that you haven't found yet) longer, and the increased volume slows heat gain. But the biggest advantage is that (assuming a tallish tank) is that it deaerates the oil. While not connected directly to volume, a tall tank will usually contain more by default. So, if you have the vertical space, use it.
