Well it might?
If you have 2500 hours experience and around 500 to 1000 hours on the type an airline is recruiting for, there may well be some opportunities with various airlines.
If you are graduating from a cadet scheme affiliated to one of the integrated training providers in conjunction with their corporate airline customers, there will probably be some steady movement.
If you are prepared to finance your own training and type related costs and assume a significant quantity of risk, there may be opportunities with a few companies who specialise in that form of "opportunity."
Beyond that, it is difficult to see what you are alluding to?
Outside of these schemes if you think airlines are going to be looking to recruit low houred, self sponsored, first officers into their normal career structures, then no, it isn't likely to happen. The days of providing some sort of "commitment" to a pilot with aspirations of qualification are a thing of the past, even in the historically rare cases where they might have occurred.
If you want to become a player in the game, then you need to bite the bullet. It is an expensive game for most people and one that is fraught with significant financial risk. Opportunities are scarce. Rewards are poor. Attrition is sizeable and significant.
There is no shortage of low houred pilots. There never has been. Those airlines that have placed warm bodies into the right seat with minimum qualification, because their preferred option of no right seat at all is not available to them, have a vast source of funded and willing applicants.
So I suppose it all depends on what you mean by "reasonable?"
