Well, here's a video example of the instrument and all I can say is wow, what a set it would make!
https://www.youtube.com/watch?v=xugbgfg371sI too found myself in this position awhile back, no
current Aeolian Skinner sample set in a large acoustic available, and I too was trying to find that one instrument that is as close to something like this example as I could, but at the same time it had to be within my budget as well.
Although nowhere near as large, it does have its similarities in sound and the large beautiful acoustic as well, so I finally settled on the Dingelsteadt from SP as being closest
and within my price range.
Otherwise I too would agree, if it's in the budget, the Salisbury by MDA would likely be the closest example you're currently going to find.
