My question is this, if the Holy Roman Empire were to federate sometime around 1400 how powerful could this eventually be?

I know it could easily dominate the medy, and probably the baltic sea;
but besides that? could it become as strong as britain was OTL?

Another question would be, eventually especially after federation it would be a kingdom I assume, so what would the name be?
I really can't think of a name besides Francia. Any ideas?
