Captain America Story Questions To Iron Out

Just some thoughts I had that I wanted to get figured out for the story purposes.

1: Regarding HYDRA's freaking laser beams, okay, we know they're on a one hit disintegration kill on humans, but what about bricks? How strong/durable would you have to be to withstand that? Like, Wonder Woman and Black Panther would be fine because of Magic Bracelets and Vibranium respectively, but what about Blob, Namor, etc?

2: Considering the number of supers on the allies side, what if...they actually manage to save Dr.Erskine from the assassination attempt? I was considering either WW or Flash being the one who saves him from the bullet, and how that could change the story.

3: Much like the The León Genetic Sequence, Infinity Formula, The KudrinTreatment, etc, the Super Soldier Serum appears to either halt or at least drastically slows down aging (Along with apparently increasing power over time in the SSS's case. Cap went from his feats in the first movie to throwing down with Ultron and Iron Man level opponents after all.)  The Super Soldier Formula permanently altered his DNA structure, esp the telomeres which govern physical ageing. The shorter they become the more the body ages. But when he ingested the SSF, it changed his DNA- his telomeres rewind constantly, which means that he can never physically age(although he CAN die, in the sense that his body suffers injury beyonds its ability to heal itself). Taking this all into account, and this fun little read, what IF: Stephanie is never frozen? I mean, we've already had a Steve go down with a plane in Diana's backstory, do we need a Stephanie to crash land? 😜
But also, because, I have this idea in my head of Diana slicing the wings off of Red Skull's ship and it's far too amusing to me.
Sooo, with her leading SHIELD, it means that HYDRA likely never gets a chance to really get a grip and the Nazi Scientists are tracked down and imprisoned. Because when you have a Stark, do you really need HYDRA?

I'd also imagine Veidt's alien plan probably doesn't get past the planning stages. If he considers it at all. Still probably ends up punching Comedian though.
