Lowering the rest mass increases atomic size. The radius of an atom is inversely proportional to the electron rest mass m, so the radius of atoms (R) would tend to infinity as m > 0. Intermolecular (London) forces are roughly proportional to the ionization energy I over R^6, and as I is inversely proportional to R, this force would also quickly go to zero as 1/R^7.

Except you won't have 0 mass.
A soon as you lower your mass to 0, you'll be flying at lightspeed, gaining relativistic mass.
'The radius of an atom is inversely proportional to the electron rest mass m, so the radius of atoms (R) would tend to infinity as m > 0'  due to the uncertainty principle, not due to mass attraction.
As to your wavefunction, the uncertainty principle allows, due to your relativistic mass, for it to be 'squished up' in a region of space not much larger than the one you now occupy (photons don't occupy infinite space for the same reason).
