Hydraulic options for John Deere 3520

[Cobb1925]

I have a 2014 JD 3520 w/factory cab. It has a 300cx loader, power beyond to operate my backhoe, a third scv to operate my hydraulic box blade, and top and tilt. I would like to purchase a 4 n 1 loader bucket but my JD dealer says I don't have enough room to add any more hydraulics. Does anyone have any ideas on how I can accomplish this.
Thanks,
Rick Sellers

A diverter valve to shift between the curl and clamshell.
