This is an interesting discussion, and I keep thinking about. As I said earlier, I'm a bit younger than the OP, but I see the writing on the wall and definitely gravitate towards more all around fitness than pure running training. Though at the moment I am still training more in the pure running realm. I might only have a few years of that left, though.
Anyways, for whatever reason, I spent what were probably my best running years (mid-20s to mid-30s) not doing any running and focusing almost primarily on strength and lifting. One of the things it took me a long time to learn in that period was that running and lifting have a ton in common. One of the big ones being that the most successful long term lifters I knew and followed spent the vast majority of their time training easy. That is around 70 percent effort and they got a lot of volume in. Longer sessions, more days per week, etc. They rarely lifted balls to the wall. But sometimes they did. And when they did, they got amazing results. Same with so many of the best runners we see. They put in a ton of time running easy at around 70 percent. They pick their truly hard efforts and races carefully.
The more I think about it, the more I think the plan you posted above will work, for about 6 weeks. Maybe as many as 10. I don't think it is a year long sustainable plan. Especially not if you want your lifting sessions to be the kind that give you that thoroughly worked and used feeling you get after running workouts.
A lot of people I knew in the general fitness lifting world would do what I said above, tons of manageable workouts with more frequency. Another crowd would get into the kind of program you posted and do them for 1-3 months. At that point, they would need to change it up to a very different program and go after different kinds of results. I think most people doing this had a lot of fun because they got to work hard more regularly and chase different goals. I'd say from an all around perspective, they were super fit. Maybe more fit than the other crowd. But they were not as strong and solid just in lifting because they weren't playing the long game.
I'd be super curious to hear a follow up in a few months with an update on however the training is going and what you find works best for you given your new goals.
