This the Republic at 100BC - roughly the time of the reforms:

So, the empire should look roughly like that when you trigger your reforms.
You should attempt to start using the first named and numbered legions when you invade Syria & Pontus (from the the section labelled "Effects of Pompey's Eastern Campaign" onwards).
You should be in the position to build the Curia Hostilia in as many provinces as possible by the time you annex Egypt and Judea, to simulate the reforms of the Roman Army instituted by Augustus (the first Emperor, who came to the throne in 27BC) - which the Curia Hostilia represents by making the regularised auxilia of the Imperial Roman Army available, as well as the later named and numbered legions equipped with Lorica Segmentata.
The historical boundaries of the empire should then be expanded as per the instructions below these three maps:

Note: as the three easternmost provinces on the last map (Armenia, Mesopotamia, and Assyria) were conquered between 113 and 117, and then abandoned by Hadrian in 118 following Trajan's death, they are beyond the historically "stable" limits of the Empire, and so are outside the Roman AOR. However, the areas between Pannonia and Dacia, and Dacia and Moesia Inferior were taken earlier, and stupidly abandoned by Hadrian (as so doing triples the length of the frontier), and Marcus Aurelius was planning their re-annexation before his death, these areas are in the Roman AOR. Hope that helps.
