That's what a lot of fan art tends to do. It certainly helps make the ship a little better looking.

This is an amazing example of "visual update" done right. That right there is a Daedalus. Exactly how a Daedalus should look. But... updated.
To answer the OP... sure? There's quite literally no information so do what you want.
In my own headcanon for the Romulan War-era, the answer would be... no. I have Daedalus-Class ships as being Romulan War era ships produced by Earth, but actually kind of garbage ships that could be cheaply and easily massed produced. Their biggest advantage was being able to spam numbers of them and were little more than mobile weapons platforms.
The "Warp 7 Beauties" would be some ship we probably haven't seen, a step between an NX and a Connie. Perhaps even something like the Walker-Class, considering it's supposed to have been an old ship as of the 2240's.
