Your Scale frame is probably lighter than your Topstone frame so could end up a lighter build, even with bigger tyres.
I’d have a play with a bike geometry calculator to try and get your Scale geometry closer to a gravel dropbar bike. Lower bottom bracket, shorter reach, lower bars…..

You could fit a rigid fork to reduce the drop at the front and make the bike handle a bit quicker. Or just reduce the travel to something like 80mm.
Chop your bars down, fit bar ends and inboard barends to get more hand positions and make it a bit more aero. I’d avoid changing to drop bars as the reach might not be great (mtbs usually have longer toptubes) and the shifters are pricey.
Fit a pair of Thunder Burts and you’ve got yourself a rapid gravel machine.
