But..... Isn't that what the OP was asking? if you simply go faster on a lightweight bike for the same amount of power, isn't that what you would want? And isn't that what you would want for race day?
Some people train using heavier, or non-aero wheels. Then they rent lightweight or aero wheels for race day. Isn't that akin to training on a heavier bike and racing on a lighter bike?
I read somewhere once that you should train with 'low technology', but race with ' high technology'. I think it may have even been said on BF.
