I think you'd find good interest in most Artocarpus (less so for breadfruit & jackfruit as they are pretty common), durian, some of the less common Baccaurea, kepel, salak, garcinia, mangifera (other than indica) etc. I think you will find interest may be higher for indigenous species - if it has been introduced there, it has probably been introduced many places and may not be that hard to find. If you can provide more information about the fruit (for example, special qualities: sweeter than typical, a different color than typical, a better flesh to seed ratio than typical, etc) it may also make it more interesting to people and they might be inclined to try it even if they already have the species.
