Fit it was me I'd look at fitting a durso standpipe into the outer box. You'll need a couple of PVC fittings that will attach to the existing standpipe. You'll need a tee, a 90' elbow and a cap plus little bit of the same diameter PVC pipe. Kevin at RC could probably fab it up from parts at his shop.
