I think so, I could use helpers on my 8" springs up front right now, but I'm not going super low because I'm prioritizing maintaining suspension geometry.
But why are you doing this? To go lower?
I won't try and pontificate about the bumpstop as I don't have a great understanding of the reality of all the variables at play yet.
But I will say this, it sounds like you can technically go lower on the fronts but don't because you want to have the springs pre-loaded. I say go max low in the front, yeah springs will be free but it's just a test, if that's too low you might be able to use the springs you have now and just add helpers. Note that if it's harsh because of the bump stop, changing spring rate will only have a minimal impact on comfort up front unless you alter the bump stop again.
If you slam it and still want to go lower (and are ok with the harshness if the bump stop is in play) then you'll need to get a shorter spring and I would say helpers are a must.

What I want is the comfort of the Group-N tophats I had, but without the issue of them raising the car so crazy high with the linear springs. With these 7" springs and those tophats, it sat at stock height with the springs barely pre-loaded (and also note, it drove great like that). I solved that by running the Ground Control camber plates, but now its uncomfortable.
I do think the spring rates are a tad soft now, so thats why the 6" springs instead but with stiffer rates. The question is if they need helper springs and which helper springs to go with.
FWIW, I'm very sensitive to changes in suspension. I've been able to notice specific differences with all sorts of parts, from individual bushings to fender braces and strut bars, and of course spring rates. Shocks I'm probably not too familiar with identifying rebound/dampening isolation but thats due to lack of experience with adjustable shocks... I have had single-adjustable shocks before and was able to dial those in (coilovers and those old AGX shocks for Imprezas).
