I am not aware of any project to implement this.

Yes, most of the terms used in this tight-binding scheme are 
already implemented in CP2K. There is a problem with the
(not so) short-range part of the Coulomb term for periodic systems
and the shell dependence. 
Still it is doable and I would expect that about have of the time
would be on putting in the atom-dependent parameters and verification
of the results. If somebody wants to help ...

Dear developers,

I hope this is the right place for such a request.

Since CP2K already has some tight-binding capabilities, it would be interesting to know if an implementation of xTB (https://www.chemie.uni-bonn.de/pctc/mulliken-center/software/xtb) will be made in the future.

Since it includes most elements of the periodic table it could be a worthwhile supplement to ab initio methods.
