Personally I think there's too much Z3 and Z4 in there, but that's your business. I'd replace one of the Z3 tempo hours with a 45 minute Z2 commute, and then come back at tempo - take a slightly longer route if you want a full hour at that intensity. In other words, incorporate some of your commuting into your training plan. Extend that principle into your recovery rides. On three days a week, your commutes can be the recovery rides you describe. That's four days commuting sorted out, without your having increased the training load.

I used to do this myself when I was commuting about 65 minutes each way. The commutes provided about 10 hours of base training per week, mostly z2 stuff. Supplementing that with a couple of interval sessions and one long ride at the weekend and I was good to go.
