Yes it is possible! I did this using a method that is a bit more complicated, but I would like to share it.

This is not my textbook, but what I saw on youtube. all credits for this lesson will go to codingwithjesse
As WiredPraire asked, I would like to show you an example
this is my index.html: 
This is the poly-react.html polymer element: 
This is my polyreact.jsx, which also has a polymer element inside

and the polymer inside jsx began to work with this transformation, which can be done using a tutorial:

The index file must also be modified as follows:

hope this helps !!!!!!!!
