Weymann 12 string parlor bridge & tailpiece

[Finger slicer]

Hello, my name's Nicola I'm a guitarist and "luthiery" enthusiast, I've bought recently a Vintage VE8000PB-12 online for the price of € 200. I was not much concerned about the condition of the guitar (that looked pretty good from pictures) and decided to take the risk. Unluckily the guitar came with a severe belly bulge that makes it really hard to play it up the 5th fret.
I know the guitar is the copy of a Weymann 12 string parlor owned by Paul Brett, but the original is coming with a tail piece. Is it possible that the decision to move the tension from the tailblock (Weymann) to the pin bridge (Vintage) caused the belly bulge ?
Anyways my question is: would it be a good idea to modify the existing bridge and add a brand new tailpiece in order to recreate the original set up of the Weymann? (6 strings fixed to the bridge e 6 going to the tail piece).
Of course reducing the bulge and regluing the bridge would be the first move.
Do you believe the problem will come up again ?
Should I give up and just add a bridge doctor ? I fear this could mute the wonderful sound this guitar has...
Thanks in advance for your comments and Sorry for my English
Nicola

It's hard to know exactly. You could move all 12 to the tailpiece, not modify the bridge, and definitely have less torque on the top.
