i think that to use snarlys snow machine might work, but i'm not sure whether the crests might have to have a seperate prop value, maybe  the option would be to make victory invisible first as the machine doesnt recognise invisibles, then set the height parameter on the machine and the apply to top surfaces only option...i spoke to snarly yesterdayy about the eureka script and it does need a sub divided plane to work and very slowly at that, just my tuppence worth
