Can you brand artifacts with Kikus pain brand?

[Konebred]

I wasn't sure and was weighting the answer to no until I found the knife of accuracy and thought that would be sorta amusing with a pain brand.

No, Gods' blessing (TSO, Kiku, Lucy) works only on non-artifact weapon - so it can only overwrite a pre-existent ego (flaming, vampiric, draining, ...)

Not even the omnipotent might of the gods is a match for the power of a crappy randart.

Randarts are the domain of the Random Number God. The Crawl gods don't stand a chance against it -- even their own powers are governed by the whims of the RNG.
