If increasing the number of places in the lattice where fusion can occur is the problem it would really just be a matter of experimentation with different techniques for allowing the lattice to be further saturated. The article seems to indicate that these results give them a clear way forward. I took the parent comment to mean that the lattice would only be essentially one time use which to me doesn't seem a problem as long as you can get sufficient energy out of it to make up for 1) using an x-ray beam to ignite the reaction and 2) the energy input necessary to create the usable lattice.
