hmm, with all that maple going on and what looks like an ebony fretboard, you're gonna get plenty of snap/cut in your tone.
I'd normally say Mules, but they might be a bit bright with all the maple. otoh, Stormy Mondays would be a little too polite imo, certainly for Angus but maybe not so much for the Kossoff/Free stuff.
I'd go with the SM neck as it's a bit sweeter than the Mule neck for those Free solo moments.
For the bridge I'd go with an AIV Mule, maybe ask for a slightly hotter wind to make the top end a wee bit fatter.
I've fancied trying a slightly overwound Mule for a while now as the stock Mule in my LP can lack a bit fullness with lower gain stuff like Free. However, if you wind up the gain a bit for AC/DC, the stock Mule is perfect.
