Custom Mollweide Projection

Question

I want to have a custom Mollweide Projection (from ESPG: 53009) in QGis, that has it's center points somwhere else than 0,0 degrees. Let's say at -10,-60 degrees.

Here is the wkt for the epsg:53009 one:

PROJCRS["Sphere_Mollweide",
    BASEGEOGCRS["Unknown datum based upon the Authalic Sphere",
        DATUM["Not specified (based on Authalic Sphere)",
            ELLIPSOID["Sphere",6371000,0,
                LENGTHUNIT["metre",1]]],
        PRIMEM["Greenwich",0,
            ANGLEUNIT["Degree",0.0174532925199433]]],
    CONVERSION["Sphere_Mollweide",
        METHOD["Mollweide"],
        PARAMETER["Longitude of natural origin",0,
            ANGLEUNIT["Degree",0.0174532925199433],
            ID["EPSG",8802]],
        PARAMETER["False easting",0,
            LENGTHUNIT["metre",1],
            ID["EPSG",8806]],
        PARAMETER["False northing",0,
            LENGTHUNIT["metre",1],
            ID["EPSG",8807]]],
    CS[Cartesian,2],
        AXIS["(E)",east,
            ORDER[1],
            LENGTHUNIT["metre",1]],
        AXIS["(N)",north,
            ORDER[2],
            LENGTHUNIT["metre",1]],
    USAGE[
        SCOPE["unknown"],
        AREA["World"],
        BBOX[-90,-180,90,180]],
    ID["ESRI",53009]]

Which parameters do I tweak and how?

I guess it must be the PRIMEM or the Longitude of natural origin but I don't know where to change the latitude.

Just changing the natural origin parameter to -60resulted in this:
