It's worth mentioning that if you have to travel between terminals, that might be an issue. IIRC, there are not uniform airside connections between the terminals and you may have to go through passport control (which you presumably can't).

It might ultimately be okay though, because it sounds like all operations have temporarily been consolidated to just 2E (Non-Schengen) and 2F (Schengen) due to Covid.

Though, as mentioned above, everything should really be on a single ticket if you go with this CDG-layover option, for the fewest possible hassles.
