I'm a UC enthusiast, I guess. I don't really know much about the other universes.
Well, like I said, the F95 isn't an official mobile suit according to the canon timeline. It's just a good idea that would fit nicely if you wanted it to. (besides, what happened to F92-8? That helps explain one of the missing links.)
I'm writing a 0079 fanfic called Gundam JACKAL. I'm still working on character profiles and canonical errors at the time, but if you want, I'll post what I've got so far in the form of a synopsis. (after I finish character bios.) I wrote a profile for a few MS for it. The RX-79(G) Special operations type, which is an RX-79(G) with the addition of a flip-down visor similar to the GM sniper custom, along with a few other differences to make it more of an efficient combat MS. Also a Mobile suit called the RX-79J JACKAL Gundam, which, in a nutshell, was built from remaining parts (among other parts built exclusively for the unit) from the downsized blue destiny project to efficiently make a mobile suit for use by the federation's JACKAL Team (the gundam JACKAL is named after it's team.)
