Well... yeah.

Those gennies are designed to take a ton of heat (which is good as those SS wicks aborb a lot). Those big ol' wicks might underperform if you run them at 8w. You can crank it full blast on a APV (say, 15w on stacked 18350s) and it's still got tons of headroom.
I am, by no means, an expert, but I would say that if you are going to run a gennie on an APV, I'd consider converting it into one of those microcoil tilt/drip hybrids with cotton (or silica). The SS mesh and cable rigs are probably best suited for power levels most regulated mods cut out before... Either a mech or something with a DNA20 chip (which can crank up to 20w, regulated...do want... they need to make a drop in version)
I gave that tilt/drip a whirl a little while back and it vaped great on my Vamo... then I tried it on my K100 and it took only a day to gunk up the cotton (due to the amount of juice that got pushed through it) so much I had to change it. So my RSST is back in mesh land now, but I'll throw a cotton MC on there at some point again.
I kind of like all the options I have now....
