yeah, I feel likes its a huge amount of work to address issues that only appear in 2-10% of games. Also, re-sale value or 'authenticity' might be impacted, although I feel like this type of machine I'd keep forever.
I own five pins and wouldn’t consider any kind of major modification like that. Regular maintenance is plenty of work without making it one of a kind. Parts are still widely available so original condition is the easiest to support.
