No. Try to layout a document on A4 while maintaining at least basic standard rules (e.g. lines of 8-12 words, a pretty text body layout, e.g. a "nice ratio" like 3/4 or 1/2, with standard margins, that is 1 on top, left and right and 2 on bottom). Since your font size will either be 11 or 12 pt on A4 because otherwise you use less than half of the paper or your font is really huge, you're not left with many options.
