That sounds like a good plan Mo and good luck with it - I'm sure it will work out.
I think all you high-milers and your big targets have done great job and admire the dedication and the self-motivation but it will never be for me.
Tbh I have no idea how anyone can do 2/3/400 miles a week and really get any cycling pleasure. After about 1.5 hours on a ride my head has had enough if I am to be frank. And to do that 2-3 times a week is enough for me - I have heaps of other stuff going on in my life. It is very easy to burn out on the enthusiasm front. Two examples:
When I moved up here I walked/scrambled/climbed every spare moment I could and then one day I was doing an ascent of Striding Edge just to see how fast I could do it and I thought "what the heck" (although I didn't use the word heck) - I had gone up and down real quick and had got home and Mrs SD asked if I had had a nice hike and I couldn't really remember much about it. I throttled back considerably and am still passionate years later.
My mate retired at 46 and he is golf obsessed - absolutely 100% obsessed. He played 4-5 times a week until Spring this year when he suddenly cut back to twice a week - he told me was getting burn't out and bored and wanted to keep the game fresh in his mind.
So - I think you have made a wise move.
