Question regarding Eyefinity + monitors with different aspect ratios

First off - I'm kind of new to the whole concept of multiple displays and Eyefinity and such, so please pardon any of my ignorance  

I was wondering if someone could provide some guidance as I am looking to give Eyefinity a try but I don't know if I will be able to do it with the hardware/setup I am planning to use. First of all, computer specs-

AMD Phenom XII 955 quad-core 3.4ghz
HIS Radeon 5770 Ice-Q Turbo 5
ASUS M4A79XTD EVO AMD 790X AM3 mobo
4GB Corsair DDR3 ram
Windows 7 Pro

So here is my predicament - I am currently running two monitors - a 22" Acer G215HV and a 17" HP L1710; aspect ratios are 16:9 and 4:3, respectively. Both monitors run fine at their native resolution; the Acer is direct DVI and the HP is DVI>VGA. Obviously, I only use the Acer when I'm gaming. Here is my question - if I were to add another HP L1710 to the left side of the Acer, would Eyefinity be able to work without messing up any of the images? So, the final arrangement would have the 22" Acer in the center running out of the DisplayPort with an active DVI adapter, and the two L1710's on either side out of the two DVI ports converted to VGA.

I know this might seem like a cheepo rig to some of you guys, but I can procure another L1710 for less than $50 online, and with the correct adapters, if this were to work, I think I could get it running for under $100. My main concern is whether or not Eyefinity would force the 22" Acer into the same resolution as the HP monitors. I know that I have read that Eyefinity 2.0 can work with screens of different sizes, but I am not sure about different aspect ratios and resolutions. I have seen people mount a large, say, 27" landscape monitor in the center of their rig with two portrait-oriented 21" or 22" monitors on either side, but I have no clue if this works with Eyefinity.

Thanks in advance for the help. I'm expecting the worst but hoping for the best. I understand that I will have to dumb down my graphics settings in CCC for everything to go smoothly in-game, but before I do anything else I would like some insight.
