Euro style/sized picks work well in american and euro locks, just be careful with them as they are a little easier bent.
Nothing wrong with larger picks though, Ive used peterson hooks(known to be large) in some very tight keyways. Chuck
Slimline picks will proabbly work the best for you. Southord has one set bigger than the one you showed us as well as a few smaller ones.

Thankx a lot for the replies! I am already lookking forward to the moment I have that set in my hands! I will definitely tell about my experiences with this toolkit.
