Stacking two 1-pole (6 dB/oct) high-pass filters is definitely an option, but it doesn’t behave exactly like a single 12 dB/oct design. The slope doubles, but the overall response (phase and the cutoff alignment) will be slightly different.
The SVF can do a true 12 dB/oct response that's mathematically “neutral”.
If you need more control over the resonance, a Sallen–Key filter is another solid choice for a 2-pole high-pass filter.
