I've decided to create this thread both to gather some community feedback on some projects on my to-do list, and also provide a central place where people working on these kind of OOBs can post their work as well.
The ones I've completed so far are:
Haiti
Dominican Republic
Philippines
Sri Lanka
My
Vietnam Total Conversion pack also features Laos (which hasn't been released as a stand-alone OOB).
Currently on my hopeful to do list are:
Mexico
Singapore
I do have a question about Singapore though. The thing that's been preventing me from starting work has been largely the debate about how to structure it. No existing OOB matches Singapore's independence dates, and prior to that it was effectively part of Malaysia. If I were to start work on such a project, would people prefer I make a separate OOB using stock Malaysian formations until Singaporean independence or would it be better to try and create a dual Malay/Singapore OOB?
