The confusion between the "register exchange" and "throat Bb venting" mechanisms has a long history - even Jack Brymer got it wrong in his book, describing the SK mechanism as having separate vents for the two functions.
I can see some issues with your proposed system, but I'm sure you'll work it out. The system you propose is actually very similar to one I've seen on a German system clarinet. My wife has a book (in German) about Oskar Oehler and his apprentices, and there is also a photo in there of something along these lines - if I have time later today I'll see if I can find that.
For my part, I devised a way to utilise the right hand index finger Eb/Bb key to open the existing side Bb vent.
This has advantages...
- no need to drill new holes, and a very straightforward mechanism with minimal adjustment required.
Two disadvantages...
- need to learn a new fingering (though, the existing fingering would still work unchanged, and not be lost)
- the trill from high C to altissimo D using the trill key would be lost
I have a plan to adapt an old Mazzeo clarinet I've got (the Mazzeo mechanism is missing some bits so happy to use it for something else), but have to convince my wife that it's worth spending money on, and my tech guy is in the middle of putting his workshop into storage for 6 months....
