I'm willing to bet that EF 2x iii + RF 2x would be considerably better than EF 2x ii + EF 2x iii - even if there was no resolution left in the base lens. You don't need the added CA and distortion from the version 2 TC:s.

I am not willing to bet because I have no doubt that the RF 2x will be better than the EF 2x ii Probably the 2x double stack doesn’t add any resolution anyway. But I can give the 2x ii + 2x iii stack a try. For the moon a filter could solve CA at the cost of (the minor) color information.
