Going from her recent battle with Doom, I think she's becoming more aggressive these days. This is also supported by the way she dealt with the Avengers over losing custody of her children, but that could have been and probably was a separate issue. All the same, she has noticeably been portrayed with more aggression these days. And, Doom did say that he detected Malice returning.
If this is current Aquaman then it's actually quite irrelevant how Invisible Woman fights since Namor is there too.
You'd need to dip into the versions of Aquaman that have potent telepathy to see his team having any chance.

What about Mera? Can't she literally manipulate the water inside a persons body to disastrous effects? After all she does have the mindset to be pretty brutal.
Who has she pulled the water trick on? Namor is..actually quite durable. For instance I don't think she could mess with him the same way she could mess with a normal person.
If she can mess with someone on the scale of Namor then it's going to really just come down to who can activate their power the quickest, Mera or Sue.
