So here's a rendition of a knotless adjustable rope bridge design that I've been playing with. This one is a 56" long Oplux with a custom sewn 13" eye (so 69" including the eye) with a stopper knot and a 60cm Beal Jammy. The Oplux is prussic hitched to my left bridge loop and the Jammy is prussic hitched to my right bridge loop (3 wraps for each), and the Jammy is tied onto the Oplux with a Kleimheist. I integrated a tender into the right side, and it's one hand adjustment for length either way, extension under load, reduction under minimum to no load. I would go with a 12" eye on the Oplux next time, and I do wish that they made a 55cm Jammy, but so far really liking this setup... I can still balance pressure on my bridge loops and it's still fairly easy to adjust when needed, it doesn't lock itself into place like Amsteel does, and way more abrasion and heat resistant.
