Correct.
One thing to consider is that the mixing of wet and dry signals in most of the common reverb circuits is done with a
differential amplifier, and the gains reflect the total series resistance of each signal. This means that the output impedance of whatever circuit you apply to the wet signal can have an effect on both the wet and dry gains. So depending on your implementation, it may be a good idea to add a buffer to the output of your extra circuit.
If you have an fx loop in the wet signal chain, you could just include an input buffer in the return. For that matter you could add an fx loop to the dry signal, too, if you really want to go nuts. That could be cool.
