I think that building an attraction based on Mordor would be do-able; I feel that Saurons Tower could easily be a drop ride named "Barad dûr-op" (‘dûr-op’ when spoken out loud sounds like ‘drop’- just a little bit of a play of words there for ya).
Here is a map below showing what I envisioned a theme park portrayal of Middle Earth - the Shire and Mordor - to look like (Bag End Barrel Adventure is a Log Flume [the map doesn’t show it very clearly, right click and 'Open image in new tab' to see an enlarged version]).
A dining in Mordor experience however would be very hard to theme IMO, all I could come up with was Orcish Offal... :blank:
