I have not played X-Wing for that long, but I was wondering if there is a squad (any faction) in Hyperspace that plays similar to how you would play Whisper, Soontir and Redline?

A starfortress, X-Wing (Poe), and A wing might be. But replacing the Phantom's movement is impossible.

Closest to decloaking movement you get is slam or double reposition preferebly with supernat reflexes.

FO silencers are expansive, but have double reposition as base.

Combine that with a Upsilon and you get something in the same ballpark atleast.

Initiative will be somewhere around 5/5/3 or 6/4/3, but it will be able to take some beating.
