Unctious, you are making excessive use of speculation here. Let's stick to definite facts that can be supported rather than accuse the dead pilots of things they may be quite innocent of! At this stage, this is rubbish:
a. It would appear that TAM Flt JJ3054 did land a little far in and a little hot.
.
b. Once established with the left-hand engine in reverse and spoilers deployed, it then became apparent to the handling pilot that a (typical Ibiza style) A320 wheel-braking failure had occurred (i.e. the never totally resolved BSCU failure mode).
.
c. Both recognizing and resolving this situation can be a very runway- (and time-) consuming affair (see link to 03 Aug 2003 accident to A320 regn C-FTDF at http://www.aaib.gov.uk/cms_resources/C-FTDF.pdf ), so the captain, being very much (and understandably) aware of the lethal lack of an overrun, decided to apply power and go-round.
.
d. The A320 Thrust reverser can take up to 5 secs to re-stow, so the application of TOGA power caused a predictable compressor surge on the LH engine well after the RH engine had gained full power, thus causing the first flash seen on the video and the divergence (due to the thrust asymmetry) well left of the centerline.
You really have no justification of bringing this up at his stage pending release of CVR and FDR evidence! It smacks of the dreadful Kenyan 737 thread where all sorts of idiots were desperately trying to stake their claim first for any of what could have been the most peculiar causes!
