Isnt this already given in a way?
We were able to farm the Ala Mhigan gear with tomes during 4.0 release and were able to upgrade them with hunt seals/books while we had Susanno to farm his weapon and Lakshmi to get accessories.
Dont think we need to uncap tomestones just to have more ilevel, unless you are speedfarming/raiding it wont matter anyway, or?
