I love arcades but the market is dead. If your doing it for the footprint sounds like a great plan if doing it for money to fund a pin sounds like a it is lose lose to me.
Really up to you and your personal likes and dislikes.
Do you still play and enjoys these great classic arcade titles? If so I would say do not do it.
If you have the money but are lacking space I would sell them in a heartbeat to by more pins.
I have owned over 40 arcades in the past 10 years just so we are clear I love them but..... pinball is far superior in most ways IMHO.
