Especially your outbound leg sounds a bit stressful to me, return should be ok. IIRC MCT T2-T1 is 2h.
From T2A, you first have to get to the CDGVAL train which connects to T1. CDGVAL is located between 2D and 2F, so either some longer walk or hop on the shuttle bus, which time-wise is maybe comparable.
Security control in T1 can sometimes be a bit of a mess.
Luggage? I won't check luggage with such a connection (On my last TATL flight, I waited 50 minutes for my luggage), even if I experienced that LH at CDG is more strict with carry-on limits than at other airports. But minor issue as you fly in J.
So overall, it will depend on the punctuality of your flight to CDG and if you arrive in a peak time or not.
