Heres the reticle Al , rotated some arbitary angle, this window would be 50% transparent and placed on top of the imaging window , reticle moved and rotated to suit via constraint handles that you can see here, Eusings Windows manager is free and deals tith transparant windows very well, Unfortnately I cannot screen capture a partially transparent window It doesnt show up at all If I try... But its very versatile the crosshai widths are easily adusted and the entire retical can be resized by dragging the constraint handles... Its a compromise of course....
