Is it sounding good now?
And yes if you want to use 11R amps (like Marshall Plexi) it will not sound good plugin 11R in front of the amp, it should be on your Fender fx return. But even plugged in the amp fx return it will be colored (for good or for bad) but you can put a parametric eq in the FX1/FX2 block and get a sound you like. Remember that a combo will never sound as a 4x12" closed back cab.

I think that using 11R as effect-only in 4CM is pretty good idea as effects are (basic but) top notch and industry standards.
