Wi requires front plates - but I haven't had one for more than 15 years with 3 different cars. I do keep a license plate under my seat so I can throw it up on the front dash if I ever get stopped. I think the likelihood of getting stopped for lack of a front plate as the only violation is quite slim - probably only going to happen if a cop is trying to radar you as you are approaching but can't get a read - and then it would probably only happen in a low traffic situation.
