Riot has mentioned (fairly early on in their development of the reworked Honor System) that they do not intend to show any meters or bars to display Honor progress.
Their main reason for this is that they do not want people to try and game the system, or turn Honor (which is meant to be a year-long climb and a display of a player's ability to play honorably) into a grind where people just want to do everything to get that meter filling out.
They're already walking a fine line with gamified Honor by giving rewards to players based on their Honor Level and where they climb to, they don't want to gamify it even more with an arbitrary meter that people are just going to work to figure out and optimize progress with.
As for validated reports adding to Honor progress, I don't like that idea, personally. On the one hand, it sounds extremely unnecessary and wholly unrelated to the Honor system. Valid reports and punishments only prove that the player in question broke the rules/was dishonorable, it doesn't say anything about how Honorable the reporting player is.
It also sounds like it'd just be adding random, arbitrary math. Like, would Honor gains increase or decrease based on level of punishment? Would I get Honor from valid (but not punishing) reports? etc.
But, even ignoring the math, I still gotta go back to my first point with it - it doesn't make sense. It's just tattle-tale brownie points that you're never really going to see, and the punishment system is largely detached from the Honor system, so...Why try to couple them?
One extra thought; giving Honor points to players whose reports result in a punishment (or whose reports turn out valid) sends a pretty bad message. Sure, at first, it would read "do the community a service and help clean up the toxics" - but, like the Tribunal, the mere incentive of seeing someone punished resulting in reward would inevitably turn the message into "report everyone to get honorable".
And that's not really a message you wanna send.
