In general what drives the low bands (especially 160m) is not more ionization. There's usually enough ionization to refract low angle 1.8 MHz RF back to Earth even during the winter at midnight at solar minimum. Absorption is the key on the low bands. With absorption proportional to the electron density, in general we want less ionization - especially in the lower ionosphere.
