That's similar to what one past client believed until a year later they were back after having blown through enough consumer displays to have already paid for the commercial displays that would still be under warranty, not to mention having to almost constantly deal with displays being out.
The general rule is actually an image height 1/6 to 1/8 the distance to the furthest viewer and I typically try to stay within 1/10 even where budget is a factor. So with a 60' to 70' viewing distance that's anywhere from a 6' or 7' high image to a 9' to 11' high image. You may be able to 'get away' with a smaller screen if you limit what is displayed and only use larger character text, but that is something you control and not a 'standard'.
A 5.5'x5.5' screen would equate to a 4.125' high (4:3 format, which is likely what you have) image, which would generally be too small for a 60' to 70' viewing distance at a 14.5:1 to 17:1 ratio. For comparison, a 70" diagonal flat screen is around a 34.3" (2.86') high image, an even greater 20:1 to 24:1+ ratio.
EasyWorship does not necessarily adjust the image, but the video card in the computer and the display can. However, that adjustment may not be a desired one. For example, if you created the content based on a 4:3 format and then display it on a 16:9 display it will likely be either pillarboxed (4:3 format image in the center with black bars to either side), stretched horizontally to fit the wider format or scaled in all directions with the top and bottom then cut off or cropped.
A bit of a warning on the installation that if you are hanging things above people's heads it is generally recommended to hire someone with the proper tools, knowledge, experience, liability coverage, etc. to handle that aspect of the work. And as either a new projector or new flat panel may entail power additions or modifications, similar for any electrical work. There are likely to be safety, code and practical aspects to consider in the installation that are best left to professionals.

I'd have to say that 16:9 is more "typical" now than 4:3, but it all depends on what you have to work with. We had a conventional 4:3 screen when we upgraded our projector and although we filled the same amount of screen width in 16:9 people seemed to prefer that the whole screen be filled so we stuck with 4:3. It's sometimes hard to explain how you spent all that money and the picture got smaller.
