Doesn't really fit Nick's MO though.
Harry. Marcone. Ivy. Goodman Grey. These are the kinds of people that Nicodemus likes to recruit- People with Will. Power. Influence. Those that can be a partner to their fallen and not merely a vessel for it. He doesn't want his Denarians to be dumb muscle- that's Tessa's style.
I see two problems with the Nicodemus/Lara scenario, and their names are Nicodemus and Lara. Yeah, he wants capable, self-controlled, effective aides...but Lara with a Coin might be a little too much of a bad thing. Yeah, he was willing to offer a Coin to Harry...but Harry isn't the sort to crave power over others for its own sake. To oversimplify, Harry doesn't particularly want to rule the world, or even Chicago.
Lara is exactly that sort. She'd be an instant rival for control.
The other is that Lara is many things, but stupid isn't one of them. Ultimately, the Coins are losing propositions, even the people who think they are in control are, in the final analysis, possessed by their Coins. I think Lara is probably smart enough to see that.
