I can't help but feel you are being wildly optimistic however I also can't help hoping like hell your evaluation is correct.
Here is to Boucher being a more offensive player in the NHL vs the junior and minor leagues!
I guess it depends on how you look at it. I tried to focus on depth players and players that had some really intriguing traits but weren't able to get a lot out of them.
For example, I suggested that Boucher could be a smaller version of Evgeni Artyukhin. Artyukhin is listed at 6'4 254 lbs so he has some size on Boucher. Boucher was listed at 6'2 205 lbs in preseason so he is only a couple of inches shorter but his peak playing weight could be as high as 225 to 230 lbs.
Here are some clips of Artyukhin:
Watching that footage, athletically speaking he had the ability to be one hell of a power forward. But if you look at his career stats, it never amounted to that much. There are likely a wide range of explanations as to why that is the case. With that said, there is still something appealing about a player with those athletic tools and that level of physicality. Under the right circumstances a player like that could be an extremely valuable depth piece.
Next, look at Martin Frk. This guy has a ridiculous shot.
One might think that with a shot like that, that Frk would score a ton of goals. When you look at his stats, he has only been able to get a few looks in the NHL where he has scored some goals but not a lot, and in the AHL he has been a decent goal scorer and only last season did he really light the lamp in an impressive way.
So even if you just merged Artyukhin and Frk into one player and Boucher became exactly that, it wouldn't be easy to tell what his production would look like. Artyukhin was an athletic freak but that didn't turn him into a premier power forward, Frk has an insane shot but he is not really thought of as an elite goal scorer.
Boucher will be a very powerful player in his prime and will likely look a lot like Ryan Reaves in terms of his athletic build. Reaves didn't have a ton of fights in juniors but ended up taking on that role as he became a pro. It was conducive with being an alpha physical player. Boucher has already demonstrated a willingness to fight and he he ends up only being a depth player he will likely fight a fair amount. We might even have a highlight clip of his like this one day:
I could still see Boucher eventually becoming a legit top six player but it would take some big development leaps. He would need to find a level of consistency that he hasn't found at this point. Also speculations of such upside are based on some intriguing tools he has and not based on current production. Like I pointed out with Artyukhin and Frk, a player can have some really intriguing tools that can make you wonder what kind of player they could be if they could put it together or consistently perform with what they show glimpses of. But just like Artyukhin and Frk, sometimes those intriguing tools don't translate into the production you would hope for.
