I'm not so sure about the Minerva/Kagura thing.

If Kagura held a real grudge against Minerva, it'd just be a repetition of her stance towards Jellal, albeit at a smaller scale.

Mistrust and dislike I would expect and approve, but an actual grudge? No thanks, at least not for me.

But I absolutely agree on the sibling reunions, though more on the Yukino and Angel one. Wally and Richard would be nice, but pretty straightforward. They are too undoubtably good guys who'll have a happy, but otherwise uneventful reunion without any surprises or uncertainties unelss there's outside interference.

The Aguira reunion though is more... thrilling I guess. We still don't know if Angel really is good now. Gaining her freedom from Brain/Zero and bringing down Zeref could both be explained with personal revenge or as her doing it for her own benefit which just happened to overlap with Jellal's goals for the moment. This uncertainty adds spice to the metting IMO.
