Looks like a good shock but I think you're going to run into too many problems to make it worthwhile, most of which you've already highlighted.

Is the length right?
What's the spring rate? Is it suitable? What linkage/rising rate is it designed for?
What's the travel? Too long/too short?
Will it clear the hollow in the swingarm?
Is the reservoir going to get in the way?
Are the mounts at each end suitable?

On the surface it seems as though the answer to most, if not all of the above, is no.

It's a nice idea, but in practice I think it'll be cheaper to buy a correctly sprung Tenere-specific shock off the shelf.

Of course, with the will to succeed and a bit of lateral thinking and the right know-how/skills, anything can be made to work, but it's going to cost money and time.
