"Assuming other dependencies allow it, this should probably take place before the Invisible Woman's costume change in Fantastic Four #387"- but you have this placed after Quasar 60 and Namor 50, and Sue is already wearing her more modest costume in those issues.
Note that the FF's roof seems to be damaged in this issue, even though repairs begun on Four Freedoms Plaza in FF 385. I guess you're assuming that it took a while to finish the repairs?
If you're treating the Black Knight's appearance as canon, then that potentially raises some continuity issues. Quicksilver is still walking with a cane in Avengers 372 as a result of Exodus's attack at the end of Bloodties and he experiences pain when he uses his powers in issue 375. In Avengers 375, Dane leaves for another dimension. So if the Black Knight appears, then this story has to take place before Avengers 375 but Pietro doesn't seem to be using a cane. I guess Pietro could have made his condition worse by acting like he was fully recovered before he was ready during this story, so he needed to use a cane in Avengers 375.
