As a general principle we will add more form factors.

For your specific example hardware, that kind of specification could be achieved using the Open Compute Micro Servers / Server Card designs, instead of the full-on 2 processor windmill designs:

As you make smaller servers, things like HA-Networking become a higher portion of the cost too, so it might be more feasible if we dropped the 2x10g Bond and went to a single 10g port for example, would losing the HA networking but having those kinds of specs be interesting to you?
