how about swapping some black springs for some blue springs, i just did this (to test out for you) and the blue spring or brown spring sorta just feel the same (almost same force anyway). so like why don't you swap out some lesser used blue springs, like the f1-f12, +,-, 1-0,alt,ctrl,win,shift,tab,caps,~,esc,arrow,prntscrn,scrool,pause,home,pgdn,up. who knows maybe you'll even like a stronger return on the spacebar/enter.
if you do all that, thats at least 40keys that can be modded to ghetto red and you can still keep the alphabet letters on your cherry blue keyboard.
