I see what you meant about having other stuff to finish before attempting to give what you and Blade were discussing in that BR "labcoat" thread a trial. Interesting setup that you're trying here as well. I'd think it should work well, as it seems to be so far.
I'm not so sure about applying the HST idea of progressive overload to RE work (using Westside terminology) though. It seems to me that if you're doing ME style work (your SST stuff) that you're already using heavier loading on the same muscle groups, so the gradually increasing loads in the "HST" or RE work are not providing a novel stimulus.
I'm doing a somewhat Westside style setup now (Jim Wendler's 5/3/1 method), and I figured that the heavy 5/3/1 (somewhat ME style) work was providing the progressive overload component, whereas the higher rep accessory work was providing the metabolic stimulus.
Of course I may be entirely wrong. I don't think anyone really knows how those things all work together. We know that progressive overload is important, a certain amount of volume / metabolic turnover is important, muscle protein synthesis is important, etc. How they all work together though in different training styles that have produced results for many is really hard to model.
Maybe if you're doing 3x the volume of "HST" work as "SST" work then progressive loading in the HST work is important even though you're already placing greater tension on the muscles with the SST work. My speculation though is that the effects of progressing the HST work is largely nullified by the heavier SST work. That doesn't mean that the HST work is not beneficial, just that using an HST style progression for it may not be so important. Increasing tonnage by adding a few reps a workout might help just as much as doing it by increasing the weights being used.
Enough rambling, it's getting late.

The SST stuff, by its nature, is low enough volume that it probably isn't going to meaningfully solicit hypertrophy gains on its own. Same idea for any "ME" work or strength work in general.
As such, I suspect that keeping the hypertrophy work progressively loaded is still the path of wisdom. Particularly because there's direct research showing that consistent increases in load keeps protein synthesis cranking along higher than keeping it the same.
Obviously, there's options in between (e.g. adding some volume as you suggested), but the path of keeping MPS as elevated as possible seems to be consistent increases in load, imho.
In the worst case scenario, I suspect that it will work no better than more gradual increases in load, and in the best case scenario, it will work better. I don't see how it "hurts" to do it either way, so to me the cost/benefit is in its favor.
