My first choice with an enlarging lens would be Schneider Componon-S. They are plasmats and I've used 135 and 150's as taking lenses. They're wonderful for that.
Checkout Freestyle Photo's APHS orthochromatic film. I have a page at my website with a formula for continuous tone with that film. Very cheap and microscopic grain. Make sure you get the box that's cut expressly for 4X5 holders. It's asa 3 so in bright sun about f22 1/2 gives an easy 3 seconds iirc. Easily done with a lens cap.
Lens cap exposures, I pull the cap loose and hover micromillimeters in front of the lens while the camera settles down, then move quickly out of the way. Jiggle all you want putting it back on.
Another tip, the Schneider Componon 135 and 150 cells will come right out of the barrel and spin into a Copal 0 shutter with no machine work required. Tektronics Polaroid used to sell a little crt camera called C4 that has a useable Copal 0 shutter. Sometimes you can get them for + or - $25 on ebay.
