I'm not an experienced acoustic builder, but I've done a bit of research for work on hybrids. I'll throw in my 2 cents, for what it's worth.
I would be concerned about structural stability. In an acoustic bridge, the strings pull up and forward at the bridge pins and push down on the saddle. Pressure is distributed across the bridge. So the strings are pulling the bridge away from the soundboard at the bridge pins, but they're simultaneously pushing the bridge pins down. On an archtop, the tailpiece is where the strings attach, and there's a reason you don't see tailpieces attached directly to soundboards. By putting the connection between the bridge and the soundboard forward of the saddles, you're taking away the part that's pushing the bridge into the soundboard. It's just trying to pull it off there, which is why you see these attached on solid bodies.
That's not to say it can't work. But you'd have a fundamental change in the way the bridge interacts with the soundboard. It wouldn't be the same "wobble" that happens with an acoustic bridge, nor would it be the down-up you get with an archtop bridge. The sound you'd get would not be like either. It would be unpredictable. You'd need to do some major reinforcing at the bridge plate, and that's going to effect the sound too.
All that being said, I like crazy ideas, and this certainly qualifies. Just think through it if you're gonna move forward. It's a BIG deviation.
