Can't be done either way. Only online chars are cross-progression and those can not be edited as they are server-side, not local.
You can obv use hero editor on PC single-player, but there is no way to get the PC single-player char over to your Ps5.
If there was a way, it would be a quick Plat trophy indeed

edit. - In theory, it may be possible to jailbreak a Ps4 to be able to take PC files, similar to how people get PC data files from Boarderlands and put it on Ps4, but then you'd be cut from using online in any capacity and if you are trophy hunting it wouldn't matter since you couldn't update it. As far as I know there is no way of doing what you are looking for. I have D2r on PC and Ps5/Ps4, no luck.
