How about this?
50k pot with 12k from the slider to each end, resulting in 9.7k overall, so a good match to the original.
The ganged capacitor can only have 180° travel whereas the pot will be 270° as I have assumed for the graph or even greater.
When the two bits are assembled, which part of the pot's travel is not used?
If you want to experiment further I'll quite happily let you have the Excel spreadsheet I wrote to calculate the response.
