Two Boxcar willies in an 18 gal. container?

I reckon 2 stupice will do ok in an 18 gallon but I'm not at all sure about boxcar willie. Now that I think of it would Amish Paste be ok?

Seems a little crowded for Box Car Willie. In a 18-gallon
self-watering container, maybe. They got to be big plants
for me, easily occupying as much space as a big refrigerator
by fall. That could be overworking a root ball that small.
Maybe if you prune each plant back to one main stem as
they grow, they would do ok.

(I have not grown Amish Paste.)

Thanks! I'm planting out tomorrow and I was worried no one would answer. Much appreciated!
