FSX to MSFS Airport Conversion

I have an old FSX airport that I would like converted/upgraded for use in MSFS. Is this possible? If so, is it an east process?

I have reached out to the original publisher seeking permission for this but to no avail. My first attempt to contact them was over a year ago. My most recent attempt to contact them was 3 weeks ago. I’ve basically been emailing them every 4 weeks for the past 13 months.

Can someone help me?
