So, according to those rumors Simon is Alucard?! Hm...My most favorite character (Simon) is actually becomes my not so favorite character.
Eh. I could stomach that.
Different timeline = different rules. More than that, I am totally OK, with such changes. It shakes things up and makes new timeline exciting and fresh to observe. I would be disappointed, if they approached Alucard the same way he was in Old Canon.
Sadly, some people will cry that "Simon = Alucard - doesn't make sense", however they should remember that it doesn't make sense in the Old Canon, in LOS story it is justified and (if pulled right) could become an interesting twist.
I believe it will test the zealousness and openmindedness of the fanbase even more so, than LOS itself. Given that all those rumors are true.
I am understand that not everybody will like those ideas, and none obligated to like it, really, but I hope people will think before declaring "sacrilige", and other stuff like that, since in reality it is not "sacrilige" against the old story (since nobody touches old story), but a mere interesting (for some) experiment
