Copy/transfer file names 1:1

Title is kinda weird but I what wish to do is duplicate multiple files' names at once ONTO another set of files, WITHOUT copying the files over (due to different in file size from A and B but requiring name to be the same)

example, I have two set of files with these names in different folders

folder A:
a1_north
b2_east
3c_south
d4_west

folder B:
q1
w2
3e
r4

I wish to duplicate the name of first file in folder A to first file in folder B and so on, ultimately ended with these files in folder B as the same name from folder A (order does not matter, though I say first file to first file, as long as names ended up in folder B its good enough):
a1_north
b2_east
3c_south
d4_west

how can the above be done aside from manually renaming them all?
