Good morning Amy, No , you can (all is possible :D) . Geoserver reproject automatically the map with your SRS.
Just change the values of your bounding box , when you use a bbox in Lat\Lon with EPSG:3572 , Geoserver thinks it's in meters. For example the max BoundingBox of the world is : -in meters : <BoundingBox SRS="EPSG:3572" minx="-20000000" miny="-20000000" maxx="20000000" maxy="20000000"/> -in Lat\Lon: <BoundingBox SRS="EPSG:4326" minx="-180" miny="-90" maxx="180" maxy="90"/> Try the BoundingBox in meters and it should works .
