Contemplating disguising a 454 as a 396. How close could I get ?

I would think you'd get so close,it would take expert to know.use the old front from the 396,water pump,pulleys and bracketry.the 396 intake and carb.the old valve covers.use it all.the harmonic balancer might give it away,I recall 454's are balanced externally so it won't look like a 396 balancer but I don't see anything else giving you trouble?
