To substitute a communal, liturgical prayer life with the catechism is likewise destructive, though if the liturgical life has been distorted, as it certainly seems to have been, maybe the catechism is the best tool you have left. But the result won’t be good.

A disconnect between the Mass and the Catechism can only be confusing and counterproductive. When you have more than one Mass, how can you have the same Catechism?

When you have more than one Mass, how can you have the same Catechism?

Quite easily, just like you can say many different prayers yet remain Orthodox Christian throughout.
