Yes I agree and AIS signal senders are inexpensive and small. It seems a good idea to me providing you can maintain the price down.
If you can make it at much lower price (as I think you can) you can also study a system based only on AIS. I know that the range is a bit less than 50 nm but sailboats are slow and that would be enough for coastal cruise where the probability of a boat or ship with AIS on a 45 nm circle is very high. After all 95% of recreational cruising is a coastal one.
Of course that would imply that the sailboat whose crew used that system would have an AIS receiver (much more expensive) but that is a useful piece of equipment and many recreational sailors are buying them.
If a kit can be made with a receiver incorporating two or three dedicated AIS senders, small ones that could be used all times by the crew on deck and that would give a distress signal of man overboard to all AIS receivers on range (including the one in the sailboat) I believe that would be a success, providing the price would not be much bigger than the receiver alone and probably that is possible.
