As far as navalized jets go, yeah, I can't see the Me-262 as one. A more believable "what-if" might be a brand-new carrier-based jet loosely based on the Me-262, but with the more substantial alterations needed for an aircraft of this nature.
If you really get into what-ifs, I find that it's one of the best and most entertaining ways to learn real history. The most believable what-ifs take quite a bit of in-depth research into what actually happened. I've fallen into the "rule of cool" trap myself on several occasions, and while it can be great for setting up some action movie or comic book themes, you inevitably sacrifice a lot of realism.
