With the Chimera, we got both Blue and Red Engines. Please make up your mind, which it supposed to be. Don't recall any canonical ship that mixes like that.
The Pujwathever, can we please get another model to choose from? I personally hate it with great distain. It looks like a BoP that crashed into a junkyard and got rear ended by a Raptor. That or some kid threw together a Klingon ship with Legos.
