Perhaps a clarification will stimulate a response. I am not talking about reverb, which is the usual way to add depth, but front-to-back placement or panning. There are various plugins which facilitate this. I'm asking if anyone has used them, and how it worked for them.
Vienna MIR Pro (also its most recent 3D version) has been invented with exactly these tasks in mind:

(... scroll down to the headline "The MIR Factor") for a short overview).
Many mistake this engine as "just another reverb", but reverb is only one of its features, and actually one that simply "happens" along the way. Primarily, MIR 3D is meant to take care for all aspects of spatialisation, both for the direct signal and the "wet" response from the space a specific instrument has been (virtually) put into.
Alan Meyerson even came up with the great idea of employing it as an efficient and automatable "front/back" panner in a mono context. 😊 He explains this unusual approach in a chat about the mix of the score for "Mank":

Don't hesitate to ask if you have further questions!
