Is it possible or with time can an aikidoka actually catch a persons wrist in the moment with a resisting atacker?
Yes, and it's also possible to actually blend with a sword so effectively that you can catch it between your palms and not get cut. Or so they say. But what's the point? Even if it can be done, it's still just a parlor trick, not a skill with practical value. Is that what you want, to learn parlor tricks?
