Howdy,
Assume here we talking perf plate other wise up riser hieght as well....
Yeh unless your second plate is adjusted for height it would suffer entrainment, to the point i reckon it would reduce plate impact so act as a single plate perhaps...go close on std spacing.
Don't see much point in holding a larger volume of later factions,/ lower quality end spirit quality on bottom plate ...top plate on a 6+ plater or more would be of more value to me but at reduced depths....ie 15mm for lower plated then step to 25mm for top plate.
Impact on run would be reverse of what you want to see...drying lower plate indicating change in factions.
Also impact on flavour retention to consider but I've never got close to those specs on any plate to test.
