As Demonspeed said, I don't think even if A.A got the spear tool and the armor from Dumas he would be able to use them. Bam or awakened Rak could, but I don't see A.A doing that without even more major asspulling.
Also, until now we haven't seen all of the powers being used at once. He only ignites one thing at a time: either black march or the first thorn. I don't remember him igniting the second one, nor do i think he has ever ignited more than one of those three things.
And also, From my memory the biggest fights bam had where he got significantly more powerful was against Data Jahad and White, and he had to awaken from a coma mid fight to get the power boost. Though I will say both were more ideological growths, with Data jahad making him seek his 'self' and White 'corrupting' him. I believe it won't be any different here.
