Long ago I took part in 'Hyboria-like' campaign - humans only and more 'alternate history' than fantasy- but Elves minis were accepted. There was not the same cornucopia of choice by then than nowadays, the Ral Partha 'Fantasy Colector' Elves were very nice figurines mixing well with the manufacturer's 'Hyborian Age' & 'Legions of the Petal Throne' and with the Minifigs (from 'Mythical Earth' to the Amazons of Aureola Rococo) & Garrison (the 'NOT Conan' Aquilanders, Nimidians, Hykranians ^-^), and on the table-top could pass for humans.
