Here is my problem. I currently receive Dish network programming via their Superdish (receive their sats 110, 119 & 121). I want to add DirecTV to receive sats 101 and 95. Because of space constraints I can't add a second dish to the balcony of my condo. Can I buy the relevant DTV LNB's, Switches and Receivers and jury rig/attach the LNB's to the existing Superdish (elliptical 36" wide and 20" high). Any input would be appreciated.
