Its your boat, rig it how you like, but my intial reaction is that this setup will have more drawbacks than advantages.
There is tension on the jib luff, but your taking all the tension that runs down the mast to the cleat and adding it to the bridle, rather than spreading it around, like the stock setup.
I thought a demasting could come from the halyard, which is way out on the front of the boat, not the most accesable place when sailing, could come loose unexpectedly and put all the rig tension suddenly on the forestay, which could fail and then, whammo, mast in your lap.
I sail my 16 solo 80% of the time and Ive found getting the jib stuck on the halyard is really only a problem in light air. Then I just scooch up front and give the halyard and jib sheet a few tugs. When the wind is up, the jib will typically pull right on over, no snags. If its does, I sheet out a bit more jib line and it will ease it over or also I just wiggle the jib halyard a bit and sail off on the new tack.
Again, your boat, and just my 2 pennies
