Realistic Finger Cymbal (zills) sf/converting .wav to .sf?

I've only recently been introduced to the world of soundfonts so this is all a bit confusing for me.
1. Does anyone know of a decent finger cymbal (zill) soundfont? The default sf on Musescore 2 just uses a horrible triangle noise
2. Is there any way to convert .wav files to soundfonts? I found really good .wav recordings of finger cymbals, and I'd love to just use those.
Help!
