XSL-FO will put widowed lines of a block at the top of the main 
reference area in the region body ... there is no way I can think of 
to push those lines below the top margin of the body.

I am not familiar with the facilities in FOP.

But you can position the background image offset from the margin of 
the region body.

The example below has the lines of text starting at 15mm from the top 
edge of the page and the image is offset higher by 20pt so you can 
see 20pts of the image above the top line.  Without the 
background-position-vertical= property of a negative value the top of 
the image would have lined up with the top line at the top of the body region.

So set your body margin where you want your text to wrap and then 
calculate a negative offset to position the top of your background higher.

I'm looking at working results in Antenna House ... I cannot vouch for FOP.

I hope this helps.
