Exploring mountainous regions (Itinerary check)

Hello everyone! My partner and I have been to Japan’s major cities (Tokyo Kyoto Osaka) at least 4 times and are looking to explore the mountainous Gifu and Hokuriku regions.

Itinerary (tentative)

Day 1: Tokyo

– arrive in Tokyo 6am
– spend full day in Tokyo
– overnight in Tokyo

Day 2: Tokyo – Takayama
– Tokyo – Takayama via Nagoya (with lunch in Nagoya), reaching late afternoon
– explore Takayama town
– overnight in Takayama

Day 3: Takayama – Kanazawa
– morning market
– lunch in Takayama/packet for shirakawago
– kiv shirakawago
– explore Kanazawa half day
– to Kyoto in the evening
– overnight in Kyoto

Day 4: Kyoto
– pre-wedding shoot!!! (Half day)
– explore Kyoto

Day 5: Kyoto
– kiv half day trip to Uji/Mt Hiei/ Kurama+Kibune

Day 6: Osaka
– spend the day shopping before leaving KIX at 6+pm

My questions are these
1) is Shirakawago worth visiting in Mid-Nov?
2) Should have our pre-wed shoot in Takayama instead of Kyoto
3) should we shorten our time for Kyoto day trips for a day trip in Takayama region instead?

I know the itinerary is very cramped
Please bear in mind that we have visited Tokyo Kyoto and Osaka multiple times previously

Thanks!
