Sounds good to me. 
You will have to experiment and determine what works best for you.
I think there are three camps regarding outdoor workouts.
Those that believe you can’t effectively do them so they free ride by feel (RPE) with XXS in mind.
Those that say you can do them as long as your route includes sections conducive to finishing sets (based on terrain and traffic) and you pick an appropriate workout.
Those that will use Xert fields on a Garmin to effectively manage focus duration as Scott demonstrates.
I’m kinda in the middle. If it’s an especially nice day I’d rather ride outdoors so I take a look at recommended workouts (all twenty) and look for something practical on the route. For example, 3-4 sets of 12 minute segments comprised of X/Y. I will try to do something similar to that during the ride. If something comes up and I fail to complete the sets I’m not overly concerned. I got a ride in that contributes to my TL so I’m happy.
