Faster than I thought it might be possible - the first draft of the PCB and the schematics in attachment.
I would be glad if you could comment if something it wrong, strange, not good or whatever.

Next steps:

1. Update the right pin positions of the TP5100 - I did not have one here
   
2. Add the layout of the XL6009 without voltage display
   
3. Print it on paper to check if holes are fitting
   
4. Order PCBs
