Angus's tone came more from hitting open chords hard into a JTM45 with the master volume (or just "volume") knob cranked, and having Malcolm on rhythm. The Dirty Fingers should do just fine if you don't go straight for preamp gain and you play hard/loud.
The DF is going to drive quickly and be more 1-dimensional.
Angus' first Sg was t-top loaded, and the main guitars he has on tour at present would have t-tops in them if they are still stock.
They are very different to a DF.....but you might be able to get 'close enough' if your style of playing his riffs is adequate.
