Dan, I'm sorry to be the bearer of bad news a second time, but if you're using the spacers to push the wide wheels out from a HF trailer, then that means you'll be moving the centreline of the wheel out from the hub. That makes an overhang that will put a bigger load on the bearings.
I doubt there would be any problem if, say, you had the 1800lb capacity trailer and only had 1000lb of trailer added to it. But if you've got the 970lb trailer and you're planning to load it right up to its limit, then the bearings could have a short life.
I don't think they would fail catastrophically, so you could just take the view that you'll replace the bearings when/if they get noisy and/or sloppy - but that could be every year in the worst case.
