We all that the HRE is hard place to expand(espcially if you're not apart of it); however, once you gain a string power base, forming the HRE is easy, somewhat to easy in my opinion. Seriously, one vassalize 4 of the 7 elcetors, you have a guranteed HRE formation(unless you are trying to roleplay). Shouldn't the elctors, regardless of v being vassalize or a junior in a PU support someone besides their overlord? That would me more historical since. What do you guys think?
