If you're up for making one go for it because most modern handles fall short, but if you don't really have experience with a proper vintage handle you may not even end up making one that's profiled any better than a modern one so it's a toss up.
Personally this axe head looks a little too worn out and I wouldn't put the effort into making my own handle for it if I actually needed an axe for something.
The poll as you know is very very severely mushroomed, but the bit has also been sharpened back an awful lot, and it looks like the eye may have been distorted some from all that hammering on the poll.
With some work it could be a decent kindling splitter, and for that you'd probably want a straight handle, which is good because straight handles are easier and modern straight handles happen to be serviceable.
