Actually did this once when the in-laws trailer broke 4 of 5 lugs on the road. We ended up taking one of the lugs from another wheel, punched it out and inserted it into the bad wheel. At least the bad wheel had 2 lugs now to keep the trailer moving. Then, it was limped to a repair shop who fixed everything for them. But, this was an older camper too. Not so sure about newer ones. Still... nothing ventured, nothing gained. If you have the luxury of experimenting in your drive way now, then do it. As you said, better in your drive way than on the road.
