The resister isn't going to use that much energy, but the effect on the response curve may be enough that you'll use up most of the range of the EQ to try to recover from it. While a slight digital EQ adjustment may improve things, pushing it to its limits may start to show the weakness.

I'd just try the straight parallel, and see if it work. It may very well be OK. It's only toward the low end of the frequency range that the impedance drops.
