First link only speaks of firearms, AND is not a Statute, but just a list of "Rules".
Second link appears to only refer to "Commercial Use" and is also not a link to a Statute.
I would suggest this...Contact your local Game Warden, (DO NOT CALL LANSING!!!), explain to them what you are wanting to do, invite them to join everyone and that you have a spare longbow and arrows for him/her to join in the fun, then ask him/her if they see a problem with it. (I suggest this because I have done it in the past and it has worked as expected). Game Wardens are our friends, and it is a good thing when people come to them with an issue that can be solved by just a simple question. Honestly, they are really good people and like to know that the public thinks highly enough of them to seek them out for guidance.
Get your answer straight from the one who will be enforcing the laws that, to be honest, we have no idea exist or not. Don't try to be a Google Lawyer (I mean that in a nice way). Let them know you don't want to break the law and are just looking for guidance.
Please let us know how that works out. I'm going to postulate that it will be a favorable outcome.
