No.

Your computer only managed to do 13 SCF steps, it would take maybe 
30-steps to reach SCF convergence and compute the total energy and force 
for the first step of vc-relax optimisation. It will take maybe 50 steps 
to find the optimal positions of all the atoms.

You should also read carefully the email from Ari, it would take less 
than 5 days and save you a lot of (computing) time.
