Test of valor is the next big gate: 3 weeks, VP cap every week after getting the quest.
Afterwords, it's secrets of the empire (20?) Fairly common, but guarenteed to get 2/week from Sha (of pride)/Lei'shen (MAX 10 weeks, likely closer to 2-4) (tot+wing 1/2 of SoO)
The next big gate are the titan runestones. Very Rare drop. Guarenteed 2/week from Sha (of pride)/Lei'shen. i'd say 3-6 weeks depending on RNG.
After that, you can use OQueue to get your celestials down.
Overall, the fastest you're clearing this is probably in the range of 10 weeks(3 months). (1 week for sigils, 3 weeks for ToV, 3 weeks for secrets, 3 weeks for runestones.) The reality will likely be 15-20 weeks, assuming you can chew through the stuff in-between the gates in a timely manner. (BP Rep, PVP quest, Change of Command, Thunder Forge, Nalak Quest, etc.)
I'd gun for the LMG at least. Sigils are easy, secrets drop in SoO. then just do wings 3/4 of ToT and 1/2 of SoO and see how long it takes to get your runestones. Runestones are really the longest part. If you're planning on raiding anyway, it'll give you something tertiary to think about.
