Is it possible to reform a 40G signal as individual 10G links?

The idea is to use a 40G QSFP multimode MTP module such as 
https://www.fs.com/products/44058.html. Then connect it using a MTP 
breakout cable such as https://www.fs.com/products/68049.html to get 
four dual fiber connectors. These are then connected to four 10G SFP+ 
multimode modules such as https://www.fs.com/products/11589.html. The 
reformer could be https://www.fs.com/products/43721.html. And finally 
the reformed signal can be transported using anything including DWDM 
modules such as https://www.fs.com/products/44058.html.

Just using fs.com as a reference to the kind of equipment I am talking 
about. Many other vendors offer simelar products.

The motivation for doing this is to get access to the many options that 
are available for 10G optics but not possible with 40G.
