Nope.

Any thoughts on restoring mini-wings on dinosaurs like T.rex, as seen in some reconstructions?  Reasonable speculation, or not particularly plausible?

Compsognathids lack wings as far as we know. Ornithomimids seem to have had them. If compies are more basal than tyrannosaurs, then it could go either way (though both Yutyrannus and Dilong seem to lack them too, no single tyrannosauroid specimen preserves a complete covering of feathers, so there's taphonomic bias here).

I think the main justification for wings on tyrannosaurids is as a hypothetical use for the small but muscular arms, though this is just idle speculation.

ornithomimids most certainly had wings, but they were shaggy and unkempt unlike their maniraptor counterparts

I would say that "enlarged feathers on the arms" is very possible for tyrannosaurs, but "wings" in the sense of those present on birds or most maniraptors is highly unlikely

amargasaurus cazaui

Authors with varying competence have suggested dinosaurs disappeared because of meteorites...God's will, raids by little green hunters in flying saucers, lack of standing room in Noah's Ark, and palaeoweltschmerz—Glenn Jepsen

That's a lot of info to get from a series of carbonized quill start gent points ;) we have no idea what ornithomimid wings looked like, I think you may be reading too much in to the speculative life restoration that came out with the press release. The artist made them look like ostrich wings because they were not for flying and also they're named ostrich dinosaurs so why not? Reasonable guess but not based on data. And many ore flight maniraptorans have more traditional looking wings.

Tyrannosaurid arms are also significantly smaller then those of Ornithomimids, thought. Then again, Caudipteryx.
