I could probably install a 4th cell holder in a CL or some other part othe rig if I need to and if the the unit does not come with one.
You can't add anything to the counterlung in this set up, just like the Mk series. The counterlung is an integral part of the ADV and OPV system and must be able to move as it's designed to.

can probably be modified with a magnetic reed switch if it gets too annoying.
Nope, magnetic reed switches are too unreliable. Just ask any PRISM owner or many classic Inspo owners. These switches break or fail to operate. There are better solutions, and they are being trialed.

The lack of potting for the electronics might be overcome if they are filled with parafin oil.
Fill that display with parafin oil and it's ruined. Parafin oil is only put inside housings that are a bit suspect as to their ability to cope with the pressure at depth. The displays in question are tested to over 600 metres in a wet chamber, there is no need for parafin filling.

To overcome this I could try installing a high pressure snubber just upstream of the manual O2 injection valve.
As per Dave above. Schareder valves are very controllable, even under high pressure.

As much as manufacturers don't like it, I still think it is a good idea to ask the tough questions, if only to find things that can be improved upon.
Absolutey, I agree 100%. Most manufacturers agree too, and take comments on board. Hey, if it has the potential to make their product better, why wouldn't they.
Cheers,
Jason.
