Just as idea. Implement to Aalto engine some eco \ lo-fi mode, wich can be more lightweight for CPU, but as optional mode ofcourse (by wish). And which would allowed the degradation of sound quality (for example sometimes I really find a cruel aliasing as a interesting FX).
Thus, i think it would be also interesting as some new timbre way (include for already existing presets, it would be fun to see to them with another angle).
And even better if such modes would be more than one :) (with different algorithms).
