I think everybody is underestimating konohamaru's chance's. there are a bunch of factors that I think gives konohamaru a slight chance even if it is little to take out pains body, which I do think he will do(there is also the strong possibility of back up so that might help but still)
1)we don't know most of konohamaru's abilities other than sexy jutsu
2)we don't know whatever naruto taught him if he taught him anything(it just said he "wanted" to teach him something
3)he outnumbers that pain body 2-1 with ebisu on his side(and possibly the second chunin because I don't think I saw him die quite yet, although I think most likely he is dead)
4)he is only against 1 pain body(kakashi and choji were against 2 of them) which is usefull because their abilities don't enhance each other(ie the god realm using grav to pull towards the weapons body)
5)I think he is against probably the weakest body in combat ability(other than the jutsu absorption one, which is actually quite usefull and possibly make this body even weaker) as this bodies only ability is stealing your soul if he touch's you, and can be disrupted and stoped by having another person throw a kunai at him forcing him to let go (ie when konohamaru through the kunai at him)
I don't think konohamaru would stand much chance 1 on 1, and he would like be crushed in like 0.00001 seconds if he was actually against more than one, but I think these factors are quite usefull, and do give konohamaru a chance of winning even if it is a slight winning. and there is still the possibility that 1 of them will die even of the other body dies aswell.
