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.
