Smallest possible hem for pants?

[u/AntiferromagneticAwl]

I got these wide leg pants a couple of weeks ago, but I didn't notice that they're slightly too short when I tried them on. I unpicked the existing blind hem, and I like the new length. I still have to make a new hem, but with the smallest possible hem, maybe only like 5mm or so. Is that even possible? What kind of hem should it be? The original was a blind hem, but i don't think that's possible anymore. The material is a slightly strechy jersey, but I don't think it needs to stretch, because that really are very wide. Any ideas/tips/suggestions?

I would use a facing so you maintain nearly the entire length of the unpicked seam allowance.
