Wow you brought back one of the threads I started back in 2012!
Hi Gord, I wouldn't go with this inline set up for a few reasons. The reason is they likely won't offer any better seal than the present stock rubber flapper in your present scuppers. They would likely also be harder to access to clean and replace as compared to the stock flapper scuppers on the outside of transom. Takes me all of 5 minutes to replace my rubber flappers.
Quite a while back I went through the same thought process you seem to be doing and bought some great quality ( edit: Stainless Steel) floor drains that had a rubber "check ball" inside. The ball would sit in the drain below floor/deck level. I figured that would be better due to easy access to the check ball to clean it of any debris or replace the ball when necessary. You could unscrew the drain screen to access the ball inside and to clean it out. Similar to the external transom ping pong style of scupper but much better access to clean due to being accessible from inside the boat and accessible without having to haul out onto the hard. They were very much the same as the Perko https://www.perko.com/catalog/category/underwater_hardware/product/447/ but much more reasonable price than the Perko. Great quality but just can't remember the brand . I will search out the name and ad a link here later (...EDIT Its Gemlux https://www.gemlux.com/89501 )
but I ended up not installing them anyway. I was concerned that water exiting the cockpit floor may at times not have enough pressure to push the check ball enough allow the deck to drain properly, especially if there was any push back on the check ball from water coming in the other way or some debris managed to jam the check ball. With the stock rubber flappers on the outside of the transom scupper I have never had a problem with my floor deck not draining properly. Even after periods of snow and ice while moored. Yes you do get a bit of water coming in when two heavy guys stand in the corner of the stern of the 228 seafarer while playing fish etc. but I felt that was the lesser of the problems. I decided to just replace my rubber flappers every 2-3 years, flush them out every trip with hose and live with the fact they don't seal out water completely when heavy guys walk to corner. When there is enough outside water back pressure the flapper will close tighter but remember the drain hose will still be almost full of water. The problem is really solved by raising the scuppers a bit higher up from water line but then the floor ultimately should be a bit higher as well. I considered ping pong style outside scuppers ( over top of present scupper) but was also concerned about drain water pressure from deck needed to push those open if they had any pressure from water on opposite side.
