  The quest to create superconductors with higher transition temperatures is as
old as superconductivity itself. One strategy, popular after the realization
that (conventional) superconductivity is mediated by phonons, is to chemically
combine different elements within the crystalline unit cell to maximize the
electron-phonon coupling. This led to the discovery of NbTi and Nb3Sn, to name
just the most technologically relevant examples. Here, we propose a radically
different approach to transform a `pristine' material into a better (meta-)
superconductor by making use of modern fabrication techniques: designing and
engineering the electronic properties of thin films via periodic patterning on
the nanoscale. We present a model calculation to explore the key effects of
different supercells that could be fabricated using nanofabrication or
deliberate lattice mismatch, and demonstrate that specific pattern will enhance
the coupling and the transition temperature. We also discuss how numerical
methods could predict the correct design parameters to improve
superconductivity in materials including Al, NbTi, and MgB2
