Eternal swan double ended vibrator - can it be used in conjunction with a Joque style harness

The title says it all, essentially Mrs Belle finds the vaginally inserted double ended dildos to be pleasurable, but can't quite hold them in use on Mr Belle. We gave up on the last one we had (not an eternal swan or feeldoe one), but stupidly chucked it before we bought the rather good Joque harness.

Can they be inserted correctly, with the shaft coming out of the O ring hole in the harness? It looks like it would be too low

Anyone used them like that?
