I doubt an airline looks at MX costs vs the acquisition cost. They are more likely to compare MX costs against the revenue that airplane is generating.
I don't know if I got you right, so apologies if you don't mean this... you say that airplane acquisition cost have no impact in the operating costs? Anyway I hope some will find the following interesting.
The costs of operating an aircraft can be divided into Direct Operating Costs (DOC) and Indirect ones (IOC). The latter are basically related to administration, passenger services (VIP lounges..), sales, marketing, etc., and the airline is responsible of them. DOC depend on the aircraft, and they include navigation fees, crew, fuel, maintenance and aircraft price dependent costs (typical breakdown).
The percentage of each factor contributing to DOC vary from aircraft to aircraft and also depend on the mission and the period of time considered. I have no exact figures, all are guesstimates, but they all show about 10% for fees, then each of crew, fuel and maintenance 20% and finally aircraft price dependent costs account for the 30%. As can be seen, the aircraft sale price has a strong effect on DOC; based on the A.I. method for estimating DOC an example shows that a 10% cheaper aircraft leads to a 4.3% reduction in DOC. An operator would be pretty interested in a cheaper airplane.
If the above figures are overall correct, maintenance costs less than the aircraft, but for a small margin. The above is also under the assumption that the appreciation period is X years; if you rise the period, I guess price-dependent costs will diminish. I would love to have more exact numbers, though.
The breakdown of DOC makes you wonder how much pilots cost too...

I recall in a neighbouring thread somewhere that for the 773ER, the engines cost more than the basic airframe (I imagine the airframe without electrical/hydraulic/avionic systems/software and customer-specific equipment). If lifetime engine maintenance costs more than the engine acquisition cost, then you are well on your way to having total maintenance costs being more than the total aircraft acquisition cost.
You're right, engines are very expensive! I could be wrong, but IIRC airframe, engines and electronics cost each 1/3 of the total price. Electronics aren't cheap either...
