I've seen a few attempts at HP/Hellsing, even wrote a short myself where Anderson happens to walk through Surrey in time to find a certain toddler on a doorstep, but there's another possible point of intersection that seems really obvious now that I thought of it: What if, instead of Cheddar, the town taken over by a vampire priest was Little Hangleton, to provide security for a certain dark ritual at the end of Harry Potter's fourth year? Once his business is complete, Alucard decides to investigate that adorable little "keep out" spell on the cemetery outside - his new childe won't be awake for some time yet, so why not have a little fun while he waits? Magic users are such an interesting challenge compared to mere walking trash ghouls, after all! Well, not really, but less utterly boring, anyway.
I think Hellsing TV would make for the more useful overall setting, with Integra jailed at the end and Seras at a loose end, so she could catch up with the Potter gang as they deal with the effects having most of the Ministry wiped out and really-hard-to-hide magic wreck a large part of London has on the Wizarding World, not even a year after several prominent Purebloods were "brutally murdered while trying to rescue the kidnapped Triwizard Champion."
