Y cable to split EV5 expression pedal for MF and PF

I want to use my EV5 expression pedal to control both my Modfactor and Pitchfactor - at the same time. Without MIDI implementation.

(I am quite happy to set up my favourite presets so that, if I want both pedals on, but only one receiving the controller data, I just edit the preset parameters so the exp control does not function. But most of the time one of the PF/MF is bypassed. If you follow...)

So, surely I can just use a Y splitter cable from the EV5...? Any reason why not?

You should be able to use a "Y" lead as long as you can avoid creating ground loops.

I was thinking I would make a little "one-stereo-in-three-stereo-out" box for this, in case I need to use the EV5 with something else as well.

(Actually I was thinking of also making the same splitter for the FS 3X 3 button footswitch I have and mounting it in the same box... but I digress)

If I was making a splitter for a pedal power cable I understand how lifting the ground on one of the connectors will eliminate ground loops, but with a passive balanced splitter like this are you hinting that there is some thing I should do to eliminate ground loops?

Thanks for the reply by the way

I can't give any hints about avoiding ground loops - each setup is a thing in itself. I just wished to alert you to a potential problem if you couple the two stomps together via a shared pedal.

Try it and see - it will probably be OK.

Nick, can you explain to me why this should work?

...others are saying it won't work and/or might damage pedals. I understand you cannot recommend I do it. But can explain how it works, how the voltage control works etc...?
