Since mono=1 and dono=2 and so on, you should change the start of Tier 2:

monillion=millillion=10^(3*10^(3*1)+3)

donillion=micrillion=10^(3*10^(3*2)+3)

tronillion=nanillion=10^(3*10^(3*3)+3)

...

deconoheptonillion=yottillion=10^(3*10^(3*17)+3)

I don't think you should make an meaningless constant(+51).
