It appears the stock 2grfe pistons have the same bore, piston pin as 2uzfe pistons while keeping the head combustion chamber design of the vvti 1uz. 1uz vvti compression height is 1.358,2uzfe is 1.335 while 2grfe is 1.23. This means you could add 2grfe pistons to the vvti 1/2uz hybrid with no machining of pistons. Alternately, the 1grfe is 1.268 which puts you very close to the 1.27 you are at after shaving 2uz pistons .06
