I’m involved with 4 groups (2 as DM, 2 as a player).Do you might find that 1 in ten player being generous) who will do something else. You need to find another two or 3. And hope not D&D they won't to play is what the others want to play.
I haven’t formed a non-D&D group since about 1994. But non-current editions? I was only using the current one from 2001-2007.It's easier to form a D&D group hope they're reliable then see if they want to do something else occasionally.
I have a stash of enough 3.5e PHB’s to go around for live play.Said books are often similar in price to a meal for 2 a drink or two and dessert.
Maybe tell them you’re playing X before, and give them the books or SRD in session 0?Because telling a group of 5-6 people who all show up with shiny new 5e books "Actually, we're going to play this game X, which you've never heard of" is a social challenge. Certainly one I've failed in the past.

You know what’s really odd to me, though? With all the talk of “5e is the only thing I can realistically get a group to play” (fair enough, I suppose - if it’s true for you, it’s true for you, though it’s a bit if self-fulfilling prophecy), why are there 4 Daggerheart threads going? I don’t even know what is, but apparently it’s popular to talk about. I’m guessing like everything else, it won’t take much market share from 5e?
