As pointed out, it is repairable but won't be cheap or simple.
If the frame is still in production, a replacement a replacement dropout can be had and bonded in place, making a good as new repair.
Or, if there's enough left, it can be modified to accept a bolt on hanger.
Or, you could fabricate a hanger and a skilled welder could attach it.
Best bet is to try real.hard not to crack it.
Note, heating it will improve the chances of straightening without cracking. But aluminum is extremely conductive, so the question is whether the bonding adhesive can take the necessary heat.
