inductor DC resistance too low for el driver IC: can I still make this circuit work?
This is from page 3 of your guide.HV830 UG

Supertex drivers allow adjustable conversion frequency (via RSW-osc),
while duty cycle is fixed at a nominal 88% ON time. When designing a
driver circuit, it is important to select the inductor and conversion
frequency to provide the required output voltage while assuring that
inductor current does not approach saturation levels.
If the inductor saturates, excessive current will flow, potentially leading &gt; to device
failure.
Ideally, inductor current should be allowed to return to zero
between cycles. If inductor current is not allowed to return to zero,
a higher average current will be needed to meet output power
requirements, increasing I2R losses, and decreasing conversion
efficiency.
On the other hand, if too much time is allowed between
zero inductor current and the start of the next cycle, more energy
will need to be transferred each cycle to maintain output power, thus
risking inductor saturation and increasing I2R and core losses.
For most applications, inductors in the range of 100µH to 1mH are
appropriate. As a general rule, larger inductor values and lower
converter frequencies should be used for lower power applications.

These notes imply that inductor value and Q may be more important than its DC resistance, which has a negative impact on Q, or inductor efficiency.
All things considered equal and no other issues, I would use inductors rated 500 mA or so and 100 uH to 1 mH, per the guidelines. If 220 uH saturated, try 330 uH, etc.
