Without entering the for or against gauges argument, what I have done on my Classic KISS is to replace the HP hose & gauges with 2 wireless transmitters to integrate with my Oceanic Atom computer.
Before you all start going on about Oceanic gear, I got this for free, and I use it in gauge mode only as my backup. HOWEVER, the only good point about it is that it can connect to up to 3 wireless transmitters and switch between them & gases (for OC divers) under water.
Therefore, I can check both my dil & O2 on my wrist with the simple push of a button (or 2).
I was at first a bit dubious about this as I thought the counterlung case might interfere with the signal, but much to my surprise I have encountered no problems whatsover with this solution to where to route hoses or whether to bother with gauges.
While I wouldn't recommend the Oceanic Atom as a standalone dive computer, I have managed to find a use for it finally
