I don't see any *inherent* problem with it, but trying it with a
standard 0.25W resistor is practically guaranteeing trouble, and
I doubt it would pass safety certification in any developed
country.

Instead use an approved resistor rated for a few thousand volts,
which might cost 10-20 cents rather than << 1 cent. Philips'
VR37 series meets the requirements, and can be bent to fit 0.5"
pitch pads.

The value should be high enough that enough current to cause
latchup will not flow *even under transient conditions*.

Best regards,
