The guitar will need to be fettled after changing strings by more than about 5%. This means the truss rod MAY need adjustment, and the intonation more than likely will too.

About 35 yrs ago, I put much thinner strings on three or four of the electrics I used most. A couple have vibratos fitted, but that doesn't have to be problematic with thinner strings. The weapon of choice still has 8, 10, 12, 22, 28, 42 on it. They get changed regularly, and the guitar is from mid '70s. Had no problems with it, saddle or nut wise, and of course, I altered the truss rod adjustment accordingly.

Yes, it doesn't sound as beefy with thinner strings, but I like the way it plays, and others have commented positively on the action.

So, from personal experience - and I've done similar on students guitars over the years - it should work fine. Bear in mind that if you decide to go back to plan A, you'll have to revert to the original set up.
