There are rubber spacers used to adapt lights, reflectors or cyclometers to different size seatpost or handlebars. One of these, perhaps trimmed to length, might work well.
There is another sensor from Velocomputer that would work with an ANT+ set up. But it's got some issues if you need BTLE support. I have one and tried it, got it to work by itself but had some conflicts with other sensors. I was primarily looking at it for BTLE support but it supposedly is ANT+ qualified.
Also, Wahoo Fitness should be releasing such a sensor by spring (rumors). It would just be a software mode on the RPM cadence sensor they have already.
The other alternative is to get the Wahoo rubber piece that holds the RPM cadence sensor to the pedal with zip ties and put that on your hub. There are also
removable zip ties you can get so you could put it on and off as many times as you wanted. That's what I'd do if you had a desire to remove it. I'm pretty sure it would fit the Garmin sensor.
The final thing you could try is to put a twist in the strap on the Garmin sensor to take up some of the slack.
