Is it possible to run 2 AMD cards on 2 different driver versions?

Here's my situation:

My system used to have an AMD Radeon HD 6450 (main) and a Nvidia 7900GT (second monitor). They were working fine together connected both to a VGA monitor, running windows 10 x64.

So I decided to replace the 7900GT with an AMD R7 250, for slightly improved gaming performance, having the R7 250 as my main card now and the HD 6450 to provide my 2nd monitor. I have to use 2 graphic cards since I am using 2 monitors that only have VGA connectors, and I couldn't find a decent card with 2x VGA or VGA + DVI-I (the R7 250 has VGA + DVI-D + HDMI).

The problem now is that I have to run both cards on the AMD Catalyst Driver version 15.20.
The HD 6450 won't work if I install the latest Crimson Drivers because it is not supported, It supports the 16.2.1 Beta driver, but with that installed the R7 250 isn't working.

Is it possible to get them working while running both on a sepperate driver, or is it actually not a problem that the R7 250 is running on an outdated driver? One thing I have noticed is that the R7 250 is not responding to clock changes I make in Graphics OverDrive, it keeps running on the default clock speeds. Besides this, is the R7 underperforming because it has an older driver?

Please don't give me answers like: "Buy a decent monitor with HDMI" I'm trying to make the most of a tight-budget gaming setup, buying a new monitor isn't really an option.

Here's the rest of my PC specs if it helps:

Windows 10 Pro 64-bit
AMD FX-6300
8GB DDR3
ASUS M5A97 R2.0
232GB+465GB HDD's

I hope someone can give me a solution, or at least an answer of whats possible, thanks in advance for reading through this :)

AFAIK, it is not possible to run two different cards from the same GPU manufacturer with different drivers. Generally speaking, you will not lose a great deal of gaming performance with an older driver, UNLESS the driver is dated before the game was released. Even then, you may not see performance issues.
 
You are going to have nothing but trouble trying to get these cards working together.
You should remove the older card and rely on the multi monitor capabilities of the R7 250.

The reason you can't find a card with two VGA connectors is because Nvidia and AMD do not support it.
They consider VGA to be legacy technology.
If you are stuck with two very old monitors, you will need an active adapter from HDMI or DVI-D to VGA.
It might be time for a new monitor.
