D.Burmanni, Spathulata, Indica, Banksii, lunata and peltata all grow with the petiolaris complex in the wild, so any of them would be fine, and tropical strains of peltata, also lunata, can happily grow without a dormancy for years, or be given a drought (as with petiolaris).
I have no experience with Hamiltonii, but I would image they would tolerate heat for part of the year but may need a cooler period in winter as they live in a much cooler region than the petiolaris complex.
My understanding of their environment is that Hamiltonii can get days as hot as 35-38C on occasion, but predominantly get much cooler days of 25-30C in summer and frost in winter, much like Cephalotus.
