I want to install a sink. The nearest pipe I can plug into is19 feet
away. The drain will be as follows:
18" drop from sink bottom to bottom of crawl space joists,
Run along bottom of joists for 19',
Rise 5" and plug into existing drain pipe within joists.
Thus, I will have no slope, but a 13" head. Will it work?

If "work" means perform to accepted standards, then no. You should
find another, lower drain to tie into. Or if structural requirements
allow, run a 1.5" drain through the joists. You could use copper DWV
to minimize the drain outer diameter.
