Looking to install mountain bar so my kid can hold on when riding

Hey guys,
Has anyone used a snowmobile mountain bar (half moon) and mounted to the handle bars (facing the rider) so that a kid riding in front of an adult can hold on to something? I took my 7 year old daughter out for a ride the other day and she kept trying to grab the handlebars or my arms…which in my opinion isn’t a good thing while you are trying to steer. If I could mount something up like this then she would be able to hold onto something….I’m not going fast anyway..but wanted to make her feel comfortable. Any thoughts?
