I made a vanilla abstraction called [DRFX] that builds a routing matrix for effects abstractions using dynamically created [send~]/[receive~] and [throw~]/[catch~] busses. You have to follow some basic naming conventions for the wireless audio busses of your inputs and effects, but then you can just tell [DRFX] the names of your inputs and effects and it creates a GUI routing matrix to control effect processing order. You can also control matrix switches via control send/receive names since it sounds like you won't want a Pd GUI. It has messages for controlling fade in/out times so that you can make transitions as desired, and there's also functionality for parameter presets and exporting/loading routing and parameter presets from text files. It's been very useful for my needs in multi-FX projects.

You can find it via deken or go to the repo here:

The help patch and INSTRUCTIONS.pdf explain the basics if you want to check it out and see if it's useful in your case.
