I don't' see that mount coming off easily. And if you do, it is surely going to scar up that nice scheme on top of the wing
This is what I would do.
Install that on the rear of the mount with the included firewall mount and use a GWS7060 sf prop.
Only other options, Cut the fuse to fit the prop, but dude..... I have no idea what that will do to its glide and flight characteristics. It wouldn't be a fair review of the plane doing that mod.
