SVS,
actually, I think it's more likely that you'll find an 8580 SID chip on those boards. There are so many C64s with that chip around that it's really easy to get anyway. Maybe the situation is different in Italy but here in Germany it's no problem to find an 8580 at all. Also, it's more likely to find the 8580 as an original replacement part/NOS (new old stock).
Plus, the old SID might draw too much power under certain conditions. That's why the "proven to work" 8580 is the better choice.
Furthermore, Solder's SID-card used the 8580 so that's the "sound" we know anyway 
I understand that you rather want to re-use chips you already have but fortunately, finding a 8580 is not like searching for a TED or an 8501. I suggest you check your boards first and see if they have a 6581 or an 8580. If you don't have an 8580 we'll find some solution by the time the cards are ready.
