I already have a 400x7 amp and I'm trying to decide if I should consider abandoning passive and move to active. I have space and WAF considerations that makes integrating 5 or 7 iNuke DSP amps a fairly difficult proposition. I know moving to an active setup would confer significant advantages for tweaking and future speaker options, but my immediate question is specifically whether you think the passive crossover you're designing will have the same SQ as an active design?
With compression drivers, active is most often a superior approach. The reality is that you need to add 2-3 passive components to deal with every response deviation you want to correct. The only practical limitation with an active crossover is the noise floor and overall quality of the DSP crossover and the amplifiers used.
The main hurdle I have to keep an eye on is insuring the time and effort is sustainable in my business. As is clear by all the responses and questions, the component/driver selection, box design, and most importantly crossover design represent the biggest value I'm adding, and is in significant demand. While I'm not out to gouge enthusiasts with audio-cable profits, it can't loose money if I want to support customers down the road and keep adding to such offerings.

An assembled crossover will likely be made available once complete, but I haven't yet settled on a compression driver. I'm leaning toward a Radian or BMS, but will be testing others as well. That said, if the cabinet differs much, the response and driver behavior can/will change. The raw MDF version of the cabinets often can come at significant savings due to the labor/time involved in finishing and cheaper sheet material costs vs. the pre-veneered material. While some will then ask why not just build the whole box, I can only attest to the huge luxury of dealing with clean, mitered corners with no MDF end grain, not dealing with non-90 deg wall construction, along with perfectly cut recesses and pre-installed T-Nuts located by a CNC.
