Merge associations with the same keys, same in a sense by user's definition

I know that it is the standard functionality of Merge to combine the values of the same keys among associations.



Now I would like to deal with a situation in which, in my associations, the keys are strings (English words). And I want to define the sameness as two words having the same result from WordStem so that "effects" and "effect" are the same key.



So is it possible for Merge to accept such a same test function for the keys, e.g., Equal@@WordStem[##]&, to determine what keys should be considered the same and be merged?



A MWE goes as below:



mergeFunc = x [Function] Total[#], Union[Flatten@#2] & @@ (x[Transpose]);

Merge["effects" -> 4, 1, 3, 5, mergeFunc]

Merge[>, <, mergeFunc]



<|"effect" -> 5, 2, 3, "effects" -> 4, 1, 3, 5|>

<|"effect" -> 9, 1, 2, 3, 5|>



The second result is desired.

Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar.
