Playing as Brandenburg and became emperor at 1460, what to do?

[Limyx826]

So somehow I became the Emperor of HRE once the Austrian Emperor died. The Imperial Incident The Shadow Kingdom is ongoing and I own most of Prussia from Teutonic Order along with Wolgast coast.

Currently drained of manpower since the last war with the teutons. I'm allied with Austria, Saxony, Mecklenburg and Poland.

Dump Poland and start expanding east. Try to hold the emperorship. When the reformation starts decide if you want to go protestant and forming prussia (giving up emp) or staying catholic and forming HRE.

Also meklenburg holds your clay, saxony too. Thats a nice hugbox you have going on there.

Couldn't be better to be honest, just exploit being the emperor to take whatever you want without worrying about unlawful territory.
Revoke any free cities that stand in your way.
Try to get Burgundian Inheritance because why not.
You could probably eat your way through most of northern Germany before reformation/not long after (depending when it spawns) - it's quite easy to diplo vassalize HRE countries as the emperor, there's probably plenty you could use for reconquest wars to mitigate the AE
You could even go for vassalizing 3 or 4 electors before reformation hits, flip protestant (lose emperorship), force convert them electors, lead the league to victory and become emperor again if that's your thing.
Otherwise you'd be nicely set up for dismantling the Empire after switching religion
