I think that a controller would be very reluctant to deny an SVFR clearance
into the zone. (Unless the weather at the field was below IFR minimums.)
Maybe a controller here can comment.

You have to have a mile viz to get a SVFR. Class D's normally do not
have radar so you have to get your SVFR from whoever runs the approach
control, although I have gotten SVFR's from class D towers immediately
upon request so I could tell they had some kind of agreement with the
approach control. A controller wouldn't hesitate to deny a SVFR
clearance if traffic won't permit it. The minimums for any instrument
approach do not factor into the equation.
