I imagine it's not that hard to roll your own, if you can find out what the details of the formats are. If it's as simple as just swapping the R and B bytes in the string, you could make an array of bytes and do some swapping.
If a spec is not readily available, I would try using a library that does the conversion for you on a very small image, and then compare the RGBA and BGRA versions and see if the bit twiddling that needs to be done is obvious (or can be deduced).
