The only way as of now to get the Honour ruleset in custom mode is to start Honour mode and then intentionally die. You will be able to modify everything except the Honour ruleset which remains and the single save option which is grayed out.
So the bosses will have their legendary actions, but you will only have one save. You can't play Honour ruleset with multiple saves as of this writing.
Next patch maybe.
Even though you'd prefer more than one save, I'd suggest giving the Honour Mode a shot. It does inhibit role playing a bit but for me, it was simultaneously the most fun/nervewracking experience I've ever had playing a video game. Really makes you think it through and roll with whatever gets thrown your way. It's a different experience, but worth it IMO. Plus you get the achievement and sick-looking die when you beat it.
