I think it would not be possible for a photon and an electron of same momentum to have same wavelength. The energy of a photon and an electron are calculated by the expressions:

Energy of a photon : E=hc / λ

Energy of an electron: E = h^2 / (2m λ^2)

Given we have the same energy, it is not possible to obtain the same value of wavelength from both equations.
