The absence of a credible Reikland candidate would then leave the Sigmarite bloc looking around for someone to support, assuming the clerical electors didn't stick to their guns with Reikland and split the Sigmarite vote. Stirland is the usual favourite for non-Reikland Sigmarite votes but there are a couple of possibilites. This might also open the door for Helmut Feuerbach to have a tilt at the title himself, and might be able to secure votes from Wissenland (as he's rumoured to be sleeping with Emmanuelle) and Hochland and Nordland (with a promise to reduce the power of Ostland). That might in turn prompt Valmir von Raukov to try to secure the nomination himself and canvass for Sigmarite support. Or the Sigmarites could even form an unholy alliance with the Ulricans and support Boris Todbringer as the lesser of two evils.
Should Karl-Franz suddenly die from pox or perhaps
a tennis accident, I think, baring as you already pointed out the confused nature of a Reikland succession, Albrecht Haupt-Anderson of Stirland is the most logical obvious winner of the Imperial Crown. The power of the Sigmarite block alone should be enough given the character and fluff presented for most of the other Electors. Albrecht is young enough for a long reign, of the right confession, and has no real challengers who, without other hypotheticals thrown in, could potentially defeat him in in said election.
Obviously if the Reikland matter were settled as to an heir, said heir is the more obvious winner being that the policy of the Reikland Emperors since Wilhelm has been to ensure the dynasty stays in control of the Imperial crown.
