Change peripheral timer in embedded software easy

I'm working on a an embedded software project for a microchip pic16f. This pic has only three timers.

Now i have a driver (let's call it driver A) that uses timer0 and timer1. Now i want to add functionality (driver b) to my program, but that requieres the use of timer1. But timer1 is already in use for driver A.

I can rewrite driver A so that it makes use of timer0 and timer2, so that driver b can use timer1.

But maybe in an upcoming project , i want to use my driver A, but with timer 1 and 2 so timer0 can be used for another driver c and having to rewrite my driver again. With three timers, there aren't many possible combinations, but even with this basic cpu I'll have many different versions of a working driver A making it impractical to manage them and fixing bugs in my code. (Imagine this driver for an mcu with more timers and even more possible ways to write Driver A)

How do you solve this problem? How can you write a driver without a hardcoded timer in it, and assign a suitable timer on initialisation? I think in c++ every timer would be an object that inherits from a timer superclass that you can pass as on object to the constructor of driverA, but i'm working in c, and therefore i can't use objects.
