The SpaceGrip is actually very versatile.
It is in 5 main parts
1. The band
2. Formed plastic base
3. A metal u shaped bracket
4.The end plastic section
5. The bar
A band can easily be replaced with a home made one, all you need is some tin snips and a quality can - cut your own, drill holes and you are sorted - you can even make one that fits around the main boom. I must admit I used two bands to ensure redundancy in case of a failure.
You can if you have a braze on, simply mount the metal bracket to the bike and then add the end piece / bar to this giving a short sturdy fitting,
Equally with a little filing you can remove a tab from the end piece. A metal strip can then be placed between the plastic base and the u shaped bracket protruding below the grip and allowing further fittings
Another option I have used is to simply mount bar with a long bolt and a few spacers.
The only real limit is your imagination!...
OH and I forgot, you can also use to fit lights above the fairing:
.. and you can fit inside the fairing to mount the GPS
