I wouldn't be happy with this. The Batman franchise already is way too all over the dcu. And there is no history or precedent for it. It would be completely from left field. I mean its laughable that dc is trying to connect Batman to Barry because they are both "detectives". Yea. Ok, DC.
I guess there might be something with Wally working with Batman during Morrisons era. If thats still canon.
But growing up I would think Batman would dislike Wally as he would most likely get Dick into fun hi jinks that the bat would disaprove of.
I think he would hate Roy. lol.
Cant remember where but there was this great flashback scene when they were kids where Roy shot Batman in the back with a trick arrow as a joke and Batman grabbed it from behind him and gave him the biggest dirty look ever. lol.
