I really like this idea. BTS is such a tangled knot at this point that I wouldn't mind starting with something simpler, continuing to believe in and work on both, and see which one is the better experiment.
One thing to consider: With dShares, screw the exchanges, but what becomes even more important here are the gateways and ramps. It does not seem to me like anyone in the BTS community has an automatic tribal opposition to this new fork idea, but hypotethically speaking, if some in the BTS community decide they won't touch the dShares fork, then there could be a problem getting gateways on board. Again, I doubt this will be an issue, but it might be best to check with the present gateways/ramps and make sure that they would be open to working with this platform as well. It certainly could be worth their while financially.
