Yes. We’re still early in the maturity of utilities. I am doing the same for my home airport KUGN. I used a freeware, and very basic utility called Airport2Project to export the FS2020 BGL into a package and went from there in the SDK. It’s not complete, but very useful for fixing most of the AI broken stuff. Search FSDeveloper’s website for information.
I’m definitely interested in other ideas too. I did a few Midwest US GA airports in XP11’s scenery gateway and I’d like to do them in FS2020 as well. I’m getting used to the FS2020 SDK now.
There is a thread here on Airport Design Editor (ADE) from FSDeveloper’s @ScruffyDuckJon as well - that app is in Alpha development stage.
