Get a second LNB and just gaffa tape it to the right of your current LNB on your existing Sky dish. You can also get a 2-way diseqc switch from Amazon for a couple of quid.
I did this during lockdown in 2020 and managed to pull it 19.2 and 28.2 off a Sky zone 1 dish. The second LNB pulls in about 60-70% signal on 19.2.
I'm in South East England, so your results may vary depending on where you are located, but it's a simple bodge job if you just want to get 3pm football from Sky Germany!
