I don't like the term, but there happens to be people's 'head canon' for ideas that won't happen in the comics other then maybe for a 2 issue Exiles story (there was an vampire Lorna in Exiles after all). There are people's ideas that are simply too complex and complicated to make it to print without a Lorna solo comic being given freedom from current thought bubbles restrictions and also being given MCU characters promotional boost and sales cut off levels.
Nothing wrong with such ideas and they can make for great fanfic, but I find it important when thinking about Lorna's steps forward how to get from point C to point A in a fashion that is possible short of banking on Kevin F. deciding in say 5 years he is going to make a Lorna solo film. In terms of the comic version going forward, its obviously easier when they get rid of the Axis retcon, but who knows when that will be.
Lorna's next push be it a mini push such as for an arc or a more substantive push as a regular needs to capture fans imagination, be willing to do things that get fans talking about the character (Lorna's last two runs had their moments, but in the end didn't really get fans outside of hard core Polaris fans talking). The success of Lorna's early 2000s story is that it did get even non-Polaris fans talking for several years about her and it opened up all sorts of doors. Whatever she does shouldn't play it safe as safe could fly in the 1991 market, but not today.
But, there is a difference between not playing it safe and damaging the character the way Milligan did or Claremont did.
