You'll please almost no one with that tack. Planescape fans are exceeded by few groups (possibly only Dragonlance fans) in their desire for fidelity to Planescape as established in 2E. Diverge from that even a little to make it more useful to a wider audience, and they'll bitterly complain.
I haven't interacted with that many Planescape fans, but of the ones that I have interacted with, I find they're most open with regard to what counts as Planescape's established conventions. If you find something works differently than you thought, chalk it up to planar misinformation. Any change is potentially true, because the story only needs to be believed for it to become true.
