Sure. You could notch that, and weld a mount/tube into the notch. Or, fab a U-shaped bracket with threaded ends (for the tank's ears), and weld the bracket in there.
FYI, I've hard-mounted tanks, but hard-mounting a tank on a buzzy XS650 made too much noise for my liking.
Might consider some way to rubber-isolate it...
