I prefer stealling what I like to put in Eberron rather then converting the entire adventure. If I have to go trought that much work, I'll just make my own campaign hahahah.You could certainly use most of Avernus without going anywhere near not just Baldur's Gate, but the Realms completely. I considered transplanting it to Eberron (Avernus is just a realm in Shavarath or something) but decided it was not worth the effort in this circumstance.
