MXR Vintage Bass Octave modification possibility

[Quatschmacher]

I’ve noticed that the switch seems to actually have four “positions” rather than simply on/off:

1. Off - main LED lit, dry signal present, unboosted;

2. main LED is lit but dry signal is muted;

3. main LED unlit, dry signal is muted;

4. main LED lit, dry signal present and mids boosted

Just wondering if there might be some way to turn the mid boost switch into a deliberate dry mute switch.
