Hotbird 13 and Astra 28.2 with the same dish?

I've never set up a satellite dish or anything as such and this will be my first time. I have an Icecrypt receiver connected to a dish, 80cm i think, pointed towards Hotbird 13e and it works fine.
However I want to get the Sky channels too which are on Astra 28.2.
Would it be possible for me to add another LNB to my current dish and receive both of them with the same dish?
If so, how hard will it be and would installing a new dish be easier?

Thanks in advance
