I would also change the font, mainly because of the unusual appearance of the 2s and 3s, which extend upwards. And the rather bold numerals are a bit much.
Look, if you consider those with an aspect ratio (width to height) of no more than 1, here's one.

Personally, I really like Monotype Corsiva, although it's a bit smaller (but it can be adjusted, I think, and super-large numerals aren't necessary). Or is it already used in Heroes? That's strange, because in the editor, with a relative size of 1.5 for Showcard Gothic and 1.65 for Monotype Corsiva, they are practically identical in height and width. If you don't make the characters bold, but in my opinion, that's not necessary.

Another interesting option is Harlow Solid Italic. I'm not sure if it fits the Heroes style, though.

And there's also the relatively strict Harrington.

It's a matter of taste, of course.
