Um um um.. Maybe? Unless those Genesis doubles aren't rated as twins. In that case no I've never clipped both ropes together because I didn't wanna fall on just one stretchy 8.5mm rope or because the route didn't wander
Got a Beal Opera 8.5mm 50m rope to use for alpine climbs. Really light (48g per meter) & rated for single, double or half. Saves 3.5 lbs vs. my 60m Mammut rope, which makes a big difference on long approaches/overnighters. The alpine climbs I do tend to be on the easier side, so I really don't take any falls (at least no whippers) but rope appears pretty durable. 50m length is sufficient for many alpine classics and helps save weight. Rope handles well and is easy to manage, which can helps on long ascents.
