You can't use high resolution images? Why? Is it a memory issue? Are the image files too large? Are they photos? Can you generate the images by program, or use a paletted PNG which will reduce down non-photographic images quite significantly?
I wouldn't expect that to fix the issue, because variants only affect the size and position of the views, not any of the other attributes, but... no harm in trying, and you never know... sometimes crazy s**t works ;-)
