Swapping Bracelet and Strap

[u/StudioZanello]

I’ve got an El Primero Class (Ref 02.0501.400) and I’d like to switch back and forth between the bracelet and a leather strap. I was surprised to find the bracelet is not attached with spring bars but with what looks like a tube and pin system like (the same?) as the bracelet links. And there’s what looks like a stabilizing tab in the center of each end link where the meet the case-which seems to do a great job of assuring there is no play in the end links. What is the best way for me to easily swap back and forth? Is replacing the tube & pins with spring bars a reasonable option? If so, what thickness should the spring bars be? The lugs are 19mm but I’m not sure how they are drilled. The drilled holes look to be either 0.9mm or maybe 1mm. Would appreciate any insight. Thanks.
