Few fixed-back seats have provisions for 3-pt belts, the vast majority have sides the are way too high and leave the lap belt not in contact with your body. I personally wouldn't take the risk on this.
Even the Recaro models you listed suffer from this. The exception would be the Recaro Pole Position ABE which I believe is only available in Europe. This is similar to the M4 GTS seat (
$$$$$$) which allows the lap belt to be used properly.
The only fixed-back seats I've seen that can safely accommodate a 3pt would be the aforementioned Recaro PP ABE, Cobra Nogaro, and Tillett B1/B5. Or the various OEM offerings (M3 CSL, M4 GTS, 991 GT2/GT3, etc.).
Edit: I'm reading now that you're 6'2". If your plan is to also find a seat that can work with a 4/5/6pt harness, be aware that seats like the Recaro PP have shoulder harness holes that I've read can be too low and thus also create a very unsafe angle.
While I've never used them, have you considered a CG-Lock with your stock seats? I've heard it's a decent half-measure and won't involve the headache of choosing an aftermarket seat entails.
