Symlink some file of a tree to another folder and conserve folder structure

Question

Assuming this tree (top-X & tX-sub-X are folders, and all sub-folder containing a .csv and various other file extensions.)

Base
├── top-1
│   ├── t1_sub-1 
│   ├── t1_sub-2 
│   └── t1_sub-3 
│
└── top-2
    ├── t2_sub-1
    ├── t2_sub-2
    └── t2_sub-3

and all sub-folder containing a .csv and various other file extensions.

can I symlink all .csv in base to another tree amd have this:

Symlinked_base
├── top-1 #directories aren't symlink
│   ├── t1_sub-1 #contains only .csv symlink
│   ├── t1_sub-2 
│   └── t1_sub-3 
│
└── top-2
    ├── t2_sub-1
    ├── t2_sub-2
    └── t2_sub-3

I can't test it now but would:

sudo find . -name "*.csv" -exec cp -Rs '{}' /path/to/Symlinked_base/

if -R is unsupported, would the following work? :

 sudo find . -name "*.csv" -exec cp -parents -s '{}' /path/to/Symlinked_base/

Stow is a package to maintain symlink trees. You can use the --no-folding option to create directories at the destination instead of linking the directories themselves - that should get you what you want.
