$60.00 is so vastly different from $14.99 that it is simple to extrapolate the answer as "no."
"Range reflects the average price of adult dinner entrées (breakfast and lunch generally cost less), except Character Dining locations, buffet locations, dinner shows, and special dining events where range reflects the average adult price of entire meal and non-alcoholic beverages. Range excludes alcoholic beverages, taxes and gratuities except at dinner shows where beer and wine, taxes and gratuities are included."
I'm reading "average price" as applying to Table Service, based on the parenthetical breakfast/lunch comment.
The Basket at The Basket is $60.00.T
The Basket accepts CS credits.
There is no mechanism in place to combine CS credits.
Therefore, no, The Basket itself cannot be purchased with CS credits.
