Not really.
Eclipse can't go monolithic. The 2 FX blocks are always alive as 2 separate units. When you load an algorithm in FX A and want to load another in B, scrolling thru the algorithms you will be prompted if they can or can't be loaded in the second block, depending on the size and resources used by the loaded one and the candidate you are looking at.
Most TF/MF algos won't allow loading of a second (=pedal) similar one.
