That's definitely a good idea, from several angles. Bigger tyres, yet another (tiny) reduction in gearing (probably offset largely by the bigger tyres), hopefully plain alloy rims.
Excellent plan!

I hope those forks don't flex.

I had that on one bike. The wheel would spin freely with the bike on the stand but I didn't realise that the flex in the fork was enough to get the tyre to rub when I was sitting on the bike. I wore a bald strip on the tyre and took the paint off the underside of the fork before I noticed!
On my wife's bike it is a good indication that the tyres need pumping out - if they don't rub they are under-inflated

I think that tiny fork-tyre clearances are potentially a serious safety risk...
I have had my tyres pick up small stones and carry them round for several wheel revs. With such a small clearance it is possible that a stone (piece of glass, or any other object picked up from the road) could wedge between the tyre and fork and jam the front wheel with obviously scary results!

In the days of more flexible steel frames a few time trialists came unstuck with fag paper clearences between front tyre and down tube. All went well till they applied the front brake with a firm squeeze...
