Ever since I played MK: Deadly Alliance and was first introduced to the fat drunken fisted, I quickly gained a likeness for him. Nothing beats an old drunken man who wields a stick and probably weighs more than your grandparents put together. Still a big fan.
But seriously, he can be a great addition to the game. The moves you suggested were awesome, maybe even going further with the puke puddle could create some sort of reset but only maybe put it in the (Vendor) variation only.
I do believe that Bo Rai' Cho has become quite the annoyance in the MK community as not many are liking guy than fan favourites such as smoke/reiko/jade probably due to his comical move set in previous arritarations. Maybe in this game, they can take a more serious approach to his character/move set as this has gone from quite a wacky game to a much more serious game with an actual storyline.
I wanna start off with his small cameo he makes near the end of the story where we actually get to see this handsome man in action and when I mean action, I mean stand up from a sitting down position (I imagine it's hard for a man who drinks a lot). His character model is perfect for this game as he's still got the chubby side to him but it's not as extreme as the previous games he's been in. The character model has already been implemented within the game so the choice is there for NR to put him in as playable. The voice is strange but I'm ok with it as he does like Santa if he spent too much time in the Asia continent. It's all there for them but they just have to be careful with what they do with his move set as if it's too silly then people will just shy him away again.

if you haven't completed the story and wanna find out the ending, don't read this cheese (don't know how to do spoiler button on iPhone).
So there's a slim chance Bo could be in this as his fan base isn't as potently strong as other characters but there could be a way to fit him in to the next game. So Cassie does her stuff and then Raiden sacrifices his man beans then becomes evil Raiden (I think) as wanting to defend earth realm now means attacking other realms will do the trick (this Raiden kicks more ass). Now it's kinda up to the remaining warriors to try and help Raiden snap out of it so why not one of the warriors be Bo Rai' Cho. Shinnok was sly in his dialogue as I though Bo was to be dead but I misread his dialogue.
"When he dies, I will claim his soul".
But when I played that whole scene back again, he's not there for the most of it so I imagine he puts himself into a ball and rolls away at turtle pace. But since his death is not stated, I assume he recovers the injuries. So MK11, no one knows the storyline but Raiden is now corrupt and cheese will hit the fan. Lui Kang and King Lao are still revenants and earthrealm needs to help Raiden. Here, Bo Rai Cho could be a great addition to the game. His motivation would probably be purely based on getting his White Locus friends back. Probably Reiko would get involved too so why not get both of them involved. Just a thought really but if he doesn't show up in MKX then he could become relevant in the next game

Now reading back, this has gotten too long. So i just want to round it off by saying that I would like to have Bo Rai Cho in the game. He's not a fan favourite but Tremor was in the first pack (strange to me but a good addition to the roster) so if that happened then any fighter could be next IMO. Just keep him like he is with the model and everything but no silly moves. Maybe the puke puddle is too silly, maybe throw alcohol in their eyes or something, seeing a chubby Bo spewing his guts out 24/7 is probably not the best way to go. I suppose it's just a waiting/guessing game when it comes to NRS and the inclusion of DLC characters. Damn that Ed and his mysterious ways.
