I am a bit lukewarm.
Intelligence is definitely the most common dump stat, even more than Charisma in 5e, so it can use some help, though it doesn't have to be necessarily by re-assigning skills.
Wisdom has all those skills partly because of the tradition trope that "dumb characters should be good at doing the right thing anyway", but it is a bit too good overall. Medicine based on Wisdom rather than Intelligence is just wrong, and bordering the miseducational, but it is sadly understandable in times like this. Wisdom is only occasionally a dump stat but not too often, mainly because low Perception means to be surprised more often, and secondarily because of mind-affecting spells.
You have 2 different but related issues at hand:
- it would be good if Intelligence was less of a dump stat
- it would be good if more non-Wizard would invest in Intelligence
If you only make skill changes (though I remind you that you don't even have to make a house rule, you can freely require Intelligence-based checks more often than Wisdom-based checks for any skill), re-assigning Perception to Intelligence is THE best shot for making it less of a dump stat, but it will also make Wisdom more frequently dumped. The other re-assignments however IMHO will only have a very small effect on increasing investments in Intelligence, except probably Survival which is a popular skill.
So overall it's not a bad idea, but for the purpose of encouraging investment, I would look elsewhere, for example replacing Dex with Int for initiative checks, or even granting bonus proficiencies based on Int.
