c) If travelling with a non-EU passport count between 5 and 20 min. to through passport control.
d) 20-30 min. till you see your luggage on the belt and then 10-15 min. walk to domestic terminal.

In other words, your minimum connection time (till check-in) will be in the range of 50-60 min. and I'm not counting any potential delay. I'd take the next flight and enjoy a cafe' and a pannino at the bar in the terminal, rather than risking your money if you have two tickets.
