Fluffwise, it sounds cool, but whether it's a useful build will depend on the forthcoming codex (probably January, just maybe November).
Will a horde of running gaunts (so "cinematic"

) actually get across the board to do some damage? Maybe...
Will
GW fix the Lictor rules? Maybe...
Personally, I suggest you buy and paint your Flyrant and maybe some gaunts, but wait for the codex before any serious investment.
