Great initiative, Erik.
As you touch upon: with an accurate DSP-replica of the passive crossover it can act as an outset or basis (saved as a preset) to experiment from, certainly to the individuals who feel confident to do so and would like to tinker on and see what may come of it.
More pressing however: a DSP-replica likely won't fully mimic the overall sonic balance and characteristics as found with the passive crossover in its stead (for several reasons, really), so there may be an element of necessity for further tweaks.
As is though it’s a welcoming helping hand to make it easier for those who are interested to venture in the direction of a DSP crossover replacing a passive ditto in their speakers.
