Not possible without modifications to crone audio process. That is straightforward but kinda involved. Also there would be performance impact, without additional architecture - all mixing routes in crone are always active and we have added many in response to similar requests.
(Here is the current routing. Would imply adding tape_eng.)
Much simpler alternative method might be adding soundfile playback directly to the engine with a few li es of sulercollider. See DiskIn helpfile.
