I get it's not a wage, but I see practical benefits for all in raising expectations and options.
Take a product like your forthcoming Pathfinder add-on. A kick-in annual royalty deal for the art and content, with a crowdsourced pre-sales campaign - looks like risks removed, everyone's in on the marketing, up-front costs gone and smiles all round if it does better than expected?
You are welcome to entertain whatever notions you wish. In my evaluation, this model has been tried, repeatedly, under ideal market conditions, and has rarely been successful for anyone involved. Pittances for writers, annoying small royalty checks for the publishers to write... it also complicates any question of reselling the work to a larger publisher, which is probably the only a small press product is going to turn into $$$bank$$$.
In my view, if you throw a couple hundred around at your writers, artists, and other freelancers, and you make your money back with a nice profit, then everyone can smile.
As for the business of being a freelancer, it is a business. If you're freelancers can't smell a dubious pot of vindaloo when you serve it to them, you may (or may not) profit from their skills in the short term, but they are going to be difficult to manage... frequently unavailable due to poor judgment in allocating their time and energies, prone to disappointment and unrealistic expectations, perhaps at risk to badmouth you on the Internet. I'd rather work with someone who knows that $25, or $250, or $2500, free and clear, is a good thing to have. That's good money for working in a hobby field, and if you plan on going full-time, you are going to need some paid gigs under your belt.
Royalties, shmoyalties.
Working for a small press is like playing a gig at the bar-laundromat; you do it for pizza money, eternal glory, and exposure. And you're happy. Or you pick a different line of work. Or you go into business for yourself.
