IIRC you can mount any of the snapshots & copy files from it without influencing the others & the thin LV itself. As for RAM caching, I'm not sure LVM would allow LVM cache residing on ram disk PV, but isin't regular Linux transparent FS access RAM caching sufficient actually ?

For some reading about LVM thin provisioning:
