Here's what I would do:

    layer.setVisibility(false);

    // wipe everything related to resolution / scale
    layer.minScale = layer.maxScale
      = layer.minResolution = layer.maxResolution
      = layer.numZoomLevels = layer.resolutions
      = layer.scales = undefined;

    // set new values
    layer.options.minScale = 15000;
    layer.options.maxScale = 500000;

    // trigger calculation with new values
    layer.initResolutions();
    layer.setVisibility(true);
    layer.redraw(); // necessary ??

I haven't tested but it should work.
