No. The FAA has a very specific checklist of items evaluated in generating the 51%. Time used does not figure in the calculation, only % of checklist items done by the builder vs the manufacturer of the kit. It is possible to buy a flying plane, modify it heavily, treat the unchanged items as kit supplied, decertify the plane, re-register it, get a new airworthiness cert, and get the repairman's cert - as long as the new work amounts to 51%, per the checklist.
