So BB-8 ptl is good, and can accomplish great things (heck I did it on an ARC-170 the other day in regular wing. And cant wait to do that in HOTAC when my group starts our net campaign...since someone made a HOTAC sheet for the ARC).
But the combo is slightly lacking to the Bwng if a person used R2D2 crew and the ptl advanced sensor combo...since its regen and the shenanigans.
Not to mention the cannon and the extra torp helps give the Bwing an edge.
Alternatively you can just take Sabine Wren's pilot ability which lets you do boost or a b-roll in any ship before movement and ptl off of that (I was doing that in my Ywing this recent campaign run through, backed up by Jake Farrell for further moving options)
I do agree that crew R2D2 isnt as good, and said that, though I again like I said before I see an argument for it over the droid if you dont have the droid.
I do say though, if you plan on giving the Bwing to players to begin with, just dont give it any points or not within 5 points of the Xwing...it is flat out better as I've eplained and I think you even agreed with me on several points on how it can be better.
The Awing flat out should be a starting ship at this point. We've had 2 other threads discussing how it needs to be either a starting ship or how to make it better, since it easily gets passed up due to damage output by all the other ships. and going full on defensive (autothrusters, etc) with it doesnt really help since usually you arent getting shot by everything on the field nor t range3 or attacked by turretsto really make the standard defenses work idealy.
I'd say:
X-wing 5 points
Awing 5
Ywing 8 (Though i think it and the Xwing should swap)
Bwing 0
Lastly, there is a facebook group that i and several others have been compiling a bunchof Scum and other Rebel and Imperial sheetsand generally useful HOTAC sources at. "Heores of the Aturo Cluster Custom Campaigns, Missions & Rules". I mention it because it seems you are looking for Scum ships.
On that note my group foudn a sheet (now on that facebook group) that has the Starviper, Mist Hunter, Scyk, and Khizrax all on it, and we playtested them and they work fine, we just made them the normal requirement of being at level 4 to swap and cost 7exp. We also did a fun side mission where we had to rescue a smuggler from mperials to unlock them.
