First of all, as soon as the new virus is introduced, the immune
system will begin fighting the virus. Thus, the virus could only be
used for a few days (I wonder what would happen in cases of AIDS).
Secondly, during HIV infection, very large amounts of lymphocytes
are made and killed every day for years. Personally, I don't think
that all HIV infected cells can be reinfected by the new virus.
Finally, the cells may be infected by another retrovirus other than
HIV which could be the source of reverse transcriptase.
I believe it has been theorized that HIV can induce apoptosis in T-cells
when interacting with the CD4 receptor... but I'm not sure...
Anyway, the only way you'll know whether or not your approach will
work is to test it...
