No, you can't reduce it to even.

The passline bet has a house edge or "charge" on it. The odds are completely even. So by taking more and more odds, you are "diluting" the house edge, but you can't eliminate it.

Think of it this way. It costs you $5 in parking to go downtown and shop. Consider this $5 parking fee the "house edge" on shopping. Now if you go downtown, pay $5 to park, and buy $5 worth of stuff --- the parking fee edge is 100%! You can reduce this, say you go and buy $100 worth of stuff. Now the parking fee only represents a 5% charge on your shopping. But it doesn't matter, even you go and buy the whole store for a million bucks, you are still out the $5 for parking. You can't make it $0, no matter how much you buy. (and you can't reduce the house edge on your wagers to 0% or less, even if you take 100x odds).
