In reply to:

and then transposing dhp (a sound, no doubt i could learn to make)


Actually, you already do. In my Hindi textbooks, the sound is described as being analagous to that produced in the phrase and how.

As for "if my audience was mostly desi," I wouldn't worry about that too much. Deis differ on how to say that word itself. Some say "deshi", others "desi". There's nothing particularly difficult about the name of Jodhpur. Just aspirate the d (which is dental, not retroflex), and you'll be pretty much on the money.
