Wooden was undersized for Barry's D and as a 3-4 DE, but he's got some length and quickness. I think the assumption was that he'd be a subpackage/depth guy until he put on additional weight and functional strength.
It's possible you could play him at end in Hafley's D, just like it's possible they could shoot Gary or LVN inside at 3T if they wanted to exploit a mismatch (although I think Wyatt et al. would be better there).

Karl Brooks played edge for Bowling Green at 300 pounds. They have some dudes in the front who are weird that way and could potentially shift around in a pinch. I suspect they don't want to do that though.

Dillard is a depth signing, he's basically a backup LT (maybe not a RT) and your 'break glass in case of emergency' Yosh Njiman type. Depending on the draft he might not make it out of camp. He was better for PHI than TEN, but he's pushing 29 so I don't think you can expect much improvement or upside.
