Go for it  

The 21-gun salute seems odd, but what the hay? If the ice is thick enough to hold up a Raptor, it will probably support an R44. Figure out a way to do it safely, like not having the truck and helicopter paths come close, use camera angles to make it appear that they are. Be ready to pull pitch if it even looks like things aren't going as planned. Rehears in advance. Seems like a goofy thing to do with a helicopter, but people do goofy things all the time. Just don't do a goofy/unsafe thing. Have fun.
