Well, that's why you are acclimated. There might be a gamerule or some other command for your playerdata that would set your tolerance if you really wanted to be an actual dwarf. However, for most purposes, you are a lowland human come to live with the dwarves, and you have to acclimate yourself to height. This would add to roleplay in my opinion.
