Finally got round to trying reshade 5.1 pretty much following gravy's instructions from way back on page 1 , the y-axis option and the swap eyes work for cab use. Overall the superdepth3d effect does seem better than the VPX version - but i suspect that part of the reason for that is that you can dial in the settings in real time so you see what the affect changes make while you do them.
Another advantage for me is that you can have the reshade effect off by default and press a button to toggle it on.
Not sure if these are any use to people but here's my ReShadePreset.ini file for superdepth settings (goes in the Visual Pinball folder)

If you do use those settings then you'll notice that i also switched to blue/amber glasses - not sure if they're colourcode or not but the colour does seem a lot better with these. The cyan/red ones i had originally didn't work well at all, but i think i messed up there - they were actually blue/red not cyan/red 
To get the reshade effect to be off by default you need to amend the ReShade.ini (also in Visual Pinball folder) and change the NoReloadOnInit line to NoReloadOnInit=1, and then assign a key to turn the effect on when you want. For that you need the keycode value, i used F16 as the key which has a keycode of 127 and changed the KeyEffects and KeyReload in the INPUT section to use that (i did that directly in the ini file as well as the settings didn't always save in the reshade gui). Note you need to press the key twice the first time to turn the effect on.
NOTE - changed lines only shown
[GENERAL]
