We've been this with MPC7s, works fine. You can squeeze the 240g out
of each PIC just fine, you simply cannot oversub.

    fpc 7 {
        pic 0 {
            port 2 {
                speed 100g;
            }
            port 4 {
                speed 10g;
            }
            port 5 {
                speed 100g;
            }
        }
    }

ports 4 and 5 in same 'group of 3', et-7/05 up at 100g and
xe-7/0/4:[0-3] up at 10g.
